Things I tried and failed at before landing on what I'm now "known" for:
An anonymous fitness Twitter account in 2012
A university degree - I dropped out after 6 months
My first job after dropping out - I got fired
Working out to look like Candice Swanepoel - she's 5'10, I'm 5'5
Failure only means you're trying.
The biggest hack is training your brain to see failures as stepping stones, not dead ends.
Enough of them and something is going to work. But if you never try, and never fail, you'll never succeed either.
