When they say the sky's the limit to me that's really true

The deeds you do may be the only sermon some persons will hear today.

It's not whether you got knocked down; it's whether you get back up.

Only in the darkness, you are able to see the stars.

If the only tool you have is a hammer, you tend to see every problem as a nail.

Question with boldness even the existence of God; because, if there be one, he must more approve of the homage of reason than that of blindfolded fear.

Climbing to the top demands strength, whether it is to the top of Mount Everest or to the top of your career.

The starting point of all achievement is desire.

What lies behind us and what lies before us are tiny matters compared to what lies within us.

We all have possibilities we don't know about. We can do things we don't even dream we can do.

Neither seek nor avoid, take what comes.

Become a possibilitarian. No matter how dark things seem to be or actually are, raise your sights and see possibilities -- always see them, for they're always there.

Look up at the stars and not down at your feet. Try to make sense of what you see, and wonder about what makes the universe exist. Be curious.

All thinking men are atheists.

He that can have patience can have what he will.

We should not give up and we should not allow the problem to defeat us.

When it comes down to it, I let them think what they want. If they care enough to bother with what I do, then I'm already better than them.

Know thyself.

The duty of youth is to challenge corruption.

If you want a thing done well, do it yourself.

There is no passion to be found playing small - in settling for a life that is less than the one you are capable of living.
