The greatest enemy to human potential is your comfort zone

Tomorrow is worth more than yesterday but less than today.

Shoot for the moon and even if you miss you’ll land among the stars/

Failure is not the opposite of success, it is part of the success.

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

You cannot escape the responsibility of tomorrow by evading it today

Don't fear failure, fear being in the same exact same place next year as you are now.

I think, therefore I am.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

The temptation to quit will be the greatest when you are about to succeed

No one starts out on top. You have to work your way up.

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

We all have two lives. The second begins when we realise we only have one. 

In order to become better than anybody else you must first become better than yourself.

Everything that happens was once a dream.
