Success is a journey, not a destination.

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

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

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

Don’t hang your targets after you’re done shooting.

Don’t be afraid to work hard and find out how good you can really be.

Everything that happens was once a dream.

Hard work beats talent when talent doesn't work hard.

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

Run in the morning before your body figures out what you're doing

Just stick with it, what seems hard now will one day be your warm up.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

There are no shortcuts to any place worth going.

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

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