Aim at the sun and you may not reach it; but your arrow will fly far higher than if you had aimed at an object on a level with yourself.
- F. Hawes

I've heard/read that quote before. It sounds good, striving for what you think is not possible and all that, but first off you're not supposed to look directly at the sun, and secondly, it's rather reckless to shot an arrow when you don't know where it's going to land.

Know your target and don't stare at the sun.
