I’ve always believed that one of the best ways to learn is by a process of trial and error. Indeed, one of my favorite poems is the following ‘grook’ by Piet Hein:
  • The road to wisdom?

  • Well, it’s plain

  • and simple to express:

  • Err

  • and err

  • and err again

  • but less

  • and less

  • and less
