Life is not measured by the breaths we take, but by the moments that take our breath.

Obstacles are those things you see when you take your eyes off the goal.

The greatest sin is to think yourself weak.

Doubt is the tax man pays for the luxury of useless knowledge.

If only we'd stop trying to be happy, we'd have a pretty good time.

Joy is the holy fire that keeps our purpose warm and our intelligence aglow.

There is no substitute for hard work.
