I have spent 11 years instilling this method into my kids, as my grandfather and father did to me.
Don't be scared to fail, try, learn, analyze, refine, repeat.
Don't let anyone tell you, you can't.
Failure is a tool, not the result...this is hacker way and applies to all in life.
Lessons learnt this way (a form of play and how children naturally learn) form the strongest pathways for learning how to learn.
A skill that is slowing being lost...
