阅读下文，然后从各顺所给的四个选项中选出一个最佳答案. 17-year-old Brennan Agranoff, a colorblind boy, started his custom sock business in middle school, with a small loan(贷款)he got from his parents. Up till now, he has sold over $1 million worth of socks online in the last four years.
Brennan thought of the idea for his custom sock company at just 13 years old. He was attending a high-school basketball game in his hometown of Sherwood, Oregon, and noticed that many kids his age were wearing the same white Nike sport socks. The boy told himself that if these white plain sacks were so popular with kids, then some cool custom designs would surely be an even greater hit.
But the boy didn't tell his parents about the business idea immediately. He spent six months researching things like printing machines and technology and drawing up a business plan. Only when he had everything planned out did he ask his parents for a loan. "They thought the idea was a little out there," Brennan recently told CNN Money, but he kept pushing, and finally received a $3,000 loan to start his company. Then he began to work on his own designs. The fact that he was colorblind didn't stop him and he has created aver 200 designs now.
Business was slow the first year, but then Brennan started pushing his HoopSwagg products heavily on the Internet. Orders soon started coming in in large numbers, and HoopSwagg became a popular brand among custom sock lovers. Right now, his designs can be found on HoopSwagg website, Amazon and eBay.
Four years after starting his business, Brennan has achieved great success while balancing(平衡)school, house chores and his social life. And he says he loved every minute of it.
