What is your biggest 'bet-on-self' move?

me: quitting my Architecture job ( after 10 years of time and money spent on being one! )

I taught myself how to code while riding subway in nyc and during lunch breaks. 

Became good enough to get my first engineering job for 30k/yr and never looked back!  It's been the 2nd best decision of my life ( no. 1 being marrying by bestie!)

It was the most stressful thing I've ever done but in the end it worked out. 

Quitting and moving to another country without having anything lined up*
