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

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.

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. 

I think, therefore I am.

Don’t be afraid to work hard and find out how good you can really be.

You can have results or excuses, not both

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

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

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

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

Time is your friend, impulse is your enemy.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

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

The journey of a thousand miles begins with one step. 

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