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

Do what you have always done and you will always be what you have always been

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

It always seems impossible until it's done.

If you want to succeed, double your failure rate.

Your attitude is everything. Pick a good one.

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

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

Don’t practice until you get it right, practice until you can’t get it wrong.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

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

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

The bad news is time flies, the good new is that you're the pilot.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.
