I can is 100 times more important than IQ.

There are no shortcuts to any place worth going.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Time is your friend, impulse is your enemy.

Skills are built not born.

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

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

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. 

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

Everything you want is on the other side of fear

Failure to prepare = preparing to fail

We all have two lives. The second begins when we realise we only have one. 

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

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