Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

Nobody said it’d be easy, they just promised it would be worth it.

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

The power of reflection is the most powerful skill you’ll learn.

Instead of finding reasons why you can't, find reasons why you can.

Skills are built not born.

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

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

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

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

Time is your friend, impulse is your enemy.

The easiest person to deceive is yourself.

We learn more from failure than we do from success.

The journey of a thousand miles begins with one step.

Tomorrow is worth more than yesterday but less than today.
