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

Success is not final, failure is not fatal.  It is the courage to continue that counts.

You can have results or excuses, not both

Patience is when you’re supposed to get mad, but you choose to understand

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

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

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

Everything that happens was once a dream.

A book a day keeps the stupidity away.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

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

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

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. 

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

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