"What do you first do when you learn to swim? You make mistakes, do you not? And what happens? You make other mistakes, and when you have made all the mistakes you possibly can without drowning -- and some of them many times over -- what do you find? That you can swim? Well, life is just the same as learning to swim! Do not be afraid of making mistakes, for there is no other way of learning how to live!"

- Alfred Adler
