Time is your friend, impulse is your enemy.

There are no shortcuts to any place worth going.

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

The master has failed more times than the beginner has even tried

Tough times never last, but tough people do.

I can is 100 times more important than IQ.

The greatest mistake we make is living in constant fear that we will make one.

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. 

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

Procrastination is the thief of time and the enemy of success.

The temptation to quit will be the greatest when you are about to succeed

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

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

Start, struggle, fail, fix and learn. Repeat.

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