Mistakes have the power to turn you into something better than you were before.

Fall down seven times, stand up eight.

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

There are no shortcuts to any place worth going.

Everything you want is on the other side of fear

Tough times never last, but tough people do.

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.

He who has begun his task is half-way done. Have the courage to begin!

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. 

You cannot escape the responsibility of tomorrow by evading it today

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

If you fail, next time fail better.

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