Controlling Paralysis by Fear
I was impressed by a recent TED talk by Tim Ferriss, the best-selling author and wealthy entrepreneur.
He has bi-polar disorder. He described how he was seconds away from committing suicide in college.
He later developed a strategy for dealing with his fears. The talk is here: https://www.garynorth.com/public/16735.cfm
The advice is sensible. If you find that your fears have kept your career on the sidelines, watch the video. Then try his technique.
