Dreams don't work unless you do.

Success is a journey, not a destination.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

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

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. The most powerful warriors are patience and time.

Tough times never last, but tough people do.

Failure is NOT your destiny. Failure is the key to success.

The power of reflection is the most powerful skill you’ll learn.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

Time is your friend, impulse is your enemy.

Never underestimate the importance of small steps. small steps = big changes. 

You cannot escape the responsibility of tomorrow by evading it today

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.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.
