The essence of learning is making mistakes, that's HOW you learn to do it right!
I have to say, I don't agree with this. We learn to do it right by doing it right, not by doing it wrong. When you do something wrong, it means you haven't learned how to do it right yet.
Is it impossible for someone to do something right without doing it wrong first? No, I don't think so. Getting it wrong is not a prerequisite for getting it right.
