When a true genius appears in the world you may know him by this sign: that all the dunces are in confederacy against him.

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!

Better to understand a little than to misunderstand a lot.

I am a part of all that I have met; Yet all experience is an arch wherethro' Gleams that untravell'd world whose margin fades Forever and forever when I move

I am a part of all that I have met; yet all experience is an arch wherethrough gleams that untravelled world whose margin fades for ever and for ever when I move.

Knowledge comes, but wisdom lingers.
