Wisdom comes from experience. Experience is often a result of lack of wisdom.

Terry Pratchett

This is one of the most fundamental lessons of motivation in my eyes.

Make mistakes! Make a lot of them and enjoy every single one.

Making no mistakes should never be the aim for not making mistake involving not trying anything new. I pitty the people who never make mistakes for making mistakes is one the best things people can do in their free time.
