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

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

Life is full of opportunities. With every opportunity that is missed, another one is born.

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.

There are no shortcuts to any place worth going.

I can is 100 times more important than IQ.

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

Everything you want is on the other side of fear

There are no bad mistakes in maths, only discoveries.

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

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

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

Success can never happen without the journey (struggle).

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

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