Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

The greatest mistake we make is living in constant fear that we will make one.

Pure mathematics is in its way, the poetry of logical ideas.

Skills are built not born.

Procrastination makes easy things hard and hard things harder.

There are no shortcuts to any place worth going.

You cannot escape the responsibility of tomorrow by evading it today

I have not failed, I've just found 10,000 ways that won't work.

Time is your friend, impulse is your enemy.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

The journey of a thousand miles begins with one step.

It is never too late to become what you might have been

You cannot start the next chapter of your life if you keep re-reading the last one.
