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

It is never too late to become what you might have been

Everything you want is on the other side of fear

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

There are no bad mistakes in maths, only discoveries.

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

I think, therefore I am.

I can is 100 times more important than IQ.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

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

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

You cannot start the next chapter of your life if you keep re-reading the last one.

If you want to succeed, double your failure rate.

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