Former Austinite Jia Jiang, a blogger and entrepreneur, undertook a bold adventure a few years back that toughened him up and led him to accept rejection.

Since then, Jiang, who now lives in Silicon Valley, has been sharing his rejection therapy knowledge with others.

For 100 days in 2012, around the Austin area, Jiang sought out rejection. He asked a stranger to borrow $100 and even asked a Krispy Kreme manager to make him a special Olympic Symbol donuts. In some cases, his unusual requests were not rejected. Krispy Kreme made him the special donuts and the video Jiang made got more than five million views on YouTube.

Listen to his TED Talk, which has been viewed more than one million times, and glean some tips on how to be vulnerable and learn to not fear rejection. Because as a startup entrepreneur, there is one thing that is certain, you will have to deal with rejection.
