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

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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

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

It always seems impossible until it's done.

We all make mistakes. What matters is how we choose to move forwards from them.

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

I have not failed, I've just found 10,000 ways that won't work.

There are no bad mistakes in maths, only discoveries.

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. 

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.

Failure to prepare = preparing to fail

Hope might be a good breakfast, but it makes a very poor dinner

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