There is no elevator to success, you have to take the stairs.

There are no shortcuts to any place worth going.

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

You can be shown the path, but only you can make the first step.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

The easiest person to deceive is yourself.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Everything that happens was once a dream.

It is never too late to turn an unproductive day into a productive one.

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

You're not in competition with anyone but yourself. Outdo your past, not other people.

The greatest enemy to human potential is your comfort zone

Dreams don't work unless you do.

If you fail, next time fail better.

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