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

You cannot escape the responsibility of tomorrow by evading it today

The wise person knows that no answer is also an answer

It always seems impossible until it's done.

There are no bad mistakes in maths, only discoveries.

Success is a journey, not a destination.

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

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

The journey of a thousand miles begins with one step. 

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

Skills are built not born.

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

Failure to prepare = preparing to fail

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

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.
