Once when I was facing a decision that involved high risk, I went to a friend. He looked at me for a moment, and then wrote a sentence containing the best advice I've ever had: Be bold and brave — and mighty (强大的) forces will come to your aid.

    Those words made me see clearly that when I had fallen short in the past, it was seldom because I had tried and failed. It was usually because I had let fear of failure stop me from trying at all. On the other hand, whenever I had plunged into deep water, forced by courage or circumstance, I had always been able to swim until I got my feet on the ground again.

    Boldness means a decision to bite off more than you can eat. And there is nothing mysterious about the mighty forces. They are potential powers we possess: energy, skill, sound judgment, creative ideas — even physical strength greater than most of us realize.

    Admittedly, those mighty forces are spiritual ones. But they are more important than physical ones. A college classmate of mine, Tim, was an excellent football player, even though he weighed much less than the average player. “In one game I suddenly found myself confronting a huge player, who had nothing but me between him and our goal line,” said Tim. “I was so frightened that I closed my eyes and desperately threw myself at that guy like a bullet（子弹） — and stopped him cold.”

    Boldness — a willingness to extend yourself to the extreme—is not one that can be acquired overnight. But it can be taught to children and developed in adults. Confidence builds up. Surely, there will be setbacks (挫折) and disappointments in life; boldness in itself is no guarantee of success. But the person who tries to do something and fails is a lot better off than the person who tries to do nothing and succeeds.

    So, always try to live a little bit beyond your abilities—and you'll find your abilities are greater than you ever dreamed.

    Here's an idea whose time has come: A flu shot that doesn't require an actual shot.

    For the first time, researchers have tested a flu vaccine patch (疫苗贴) in a human clinical trial and found that it delivered as much protection as a traditional injection with a needle. Doctors and public health experts have high hopes that it will increase the number of people who get immunized (免疫的) against the flu.

    Seasonal flu is responsible for up to half a million deaths around the world each year according to the World Health Organization. A team led by Georgia Tech engineer Mark Prausnitz has come up with an alternative method that uses “microneedles”. These tiny needles are so small that 100 of them, arranged in order on a patch, can fit under your thumb (拇指).Yet they're big enough to hold vaccine for three types of flu.

    None of the study volunteers had serious side effects. The groups that got patches had mild skin reactions that were not seen in the regular needle group, while the volunteers in the regular needle group were more likely to experience pain. Overall, 70 percent of the volunteers who got vaccine patches said they'd rather use them again than get a traditional flu shot. The study authors declared it a success on all fronts.

    The biggest beneficiaries could be people in low- and middle-income countries, where flu vaccines are hard to come by. Reducing pain is nice, but other benefits—the patch costs less，is easier to transport, doesn't require refrigeration, can be self - administered and doesn't cause waste of needles—are even better.

    “Microneedle Patches have the potential to become ideal candidates for vaccination programs,” wrote Katja Hoschler and Maria Zambon of Public Health England.

    When you cross deep water driving too fast, you risk splashing water up into the air box and having it get sucked into the internal engine, which is more common than you think. There are a few steps you should take to clear the water out before you try to start it:

    ⒈First, drain the fuel tank, fuel lines and the oil. While it's draining, put a fan on the wiring and dry it out. Remove and clean the carburetor (化油器).

    ⒉Take the plugs out of the engine and turn it over to force any water out. Water will come out with the oil. Add oil to the engine and turn it over again, without the plug in. Let it sit for a while, then observe the oil to tell if there's any water in it (it will look like a white milky substance if there is water mixed with the oil). If it's there, drain it again and start over until there is little or no white showing in the oil.

    ⒊Now re-install the spark plug, add gas, then try to start the engine. You should have a can of ether (乙醚) handy just in case it's stubborn, but don't use too much. If it starts, let it run for a few minutes without making it work faster.

    ⒋After it runs for several minutes, shut it off, drain the oil and change the filter(过滤网). Run it again for a few minutes then shut it off and checks again for milky colored oil. If you have none, you should be good to go.

    ⒌If you cannot start the engine, you may have already ruined it and you will probably need to seek a professional to repair it, or, more likely, you'll have to replace it.

    My First Marathon

    Three weeks before my first marathon, one of my ankles was injured and this meant not running for two weeks, leaving me only one week to train. Yet, I was determined to go ahead.

    I remember back to my 7th year in school. In my first P.E. class, the teacher required us to run laps and then hit a softball. My performance was really terrible. He later informed me that I was "not athletic".

    The idea that I was "not athletic" stuck with me for years. When I started running in my 30s, I realized running was a battle against myself, not about competition or whether or not I was athletic. It was all about the battle against my own body and mind. A test of wills!

    The night before my marathon, I dreamt that I couldn't even find the finish line. I woke up sweating and nervous, but I was ready to prove something to myself.

Shortly after crossing the start line, my shoe laces became untied. So I stopped to readjust. Not the start I wanted!

    At mile 3, I passed a sign: "GO FOR IT, RUNNERS!"

    By mile 17, I became out of breath and the once injured ankle hurt badly. Despite the pain, I stayed the course walking a bit and then running again.

    By mile 21, I was starving!

    As I approached mile 23, I could see my wife waving a sign. She is my biggest fan. She never minded the alarm clock sounding at 4 a.m. or questioned my expenses on running.

    I was one of the final runners to finish. But I finished! And I got a medal. In fact, I got the same medal as the one that the guy who came in first place had.

Determined to be myself and move forward, free of shame and worldly labels(世俗标签), I can now call myself a "marathon winner".

Ecobee3 Smarter WiFi Thermostat

    Smart thermostats have become the face of smart home technology for most, but depending on what your home is like, it's possible to say the ecobee3 is superior.

    Most of the smart thermostats carry the same benefits, including the ecobee3. They can learn your preferences and schedules, and then adjust the temperature accordingly. They're better-looking and more enjoyable to use than the basic pieces of plastic that occupy most households. Their very presence will probably make you more conscious about saving energy. And once you're able to heat up or cool down your house from your phone, without having to get out of bed, you won't want to go back.

    If you live in a larger household, the ecobee3 can be much more convenient—provided you pick up a couple more remote sensors. Yes, it gets pretty expensive at that point, but having those gives you effective control over the temperature in different rooms around your house. In comparison, other thermostats' measurements are largely limited to the area in which they' re installed (安装).

    If you live in a smaller place, that's no big deal; the ecobee3 still has distinct advantages. It is touch-enabled and more spacious, making it less annoying when you want to enter a WiFi password, see weather information, and so on. Still, all the smart thermostats are pretty great. Which one is best just depends on whether you need a whole-home solution or a more straightforward one. For now, if it's the former, go with the ecobee3.

    If you think can-do, and you're creative and persistent, it's amazing what you can accomplish. During college, I remember being told that to fulfill my language requirement, I would "have to" take a class that I had no interest in and was meaningless to me. Instead of taking this class, however, I decided to create my own. So I put together a list of books I would read and the assignments I would do and found a teacher to sponsor me. I then went to the dean of the school and presented my case. He bought into my idea and I completed my language requirement by taking my self-built course.

    American aviator Elinor Smith once said, "It has long since come to my attention that people of accomplishment rarely sat back and let things happen to them. They went out and happened to things."

    It's so true. To reach your goals in life, you must seize the initiative. If you're feeling bad about not being asked out on dates, don't just sit around and sulk, do something about it. Find ways to meet people. Be friendly and try smiling a lot. Ask them out. They may not know how great you are.

    Don't wait for that perfect job to fall in your lap, go after it. Send out your resume, network, volunteer to work for free.

    If you're at a store and need assistance, don't wait for the salesperson to find you, you find them.

    Some people mistake can-do for being pushy, aggressive, or obnoxious. Wrong. Can-do is courageous, persistent, and smart. Others think can-do people stretch the rules and make their own laws. Not so. Can-do thinkers are creative, enterprising, and extremely resourceful.

    George Bernard Shaw, the English playwright, knew all about can-do. Listen to how he said it: "People are always blaming their circumstances for what they are. I don't believe in circumstances. The people who get on in this world are the people who get up and look for the circumstances they want, and if they can't find them, make them."
