Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

It always seems impossible until it's done.

If you can understand just one thing thoroughly, then you will understand everything.

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

I have not failed, I've just found 10,000 ways that won't work.

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

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

We all have two lives. The second begins when we realise we only have one. 

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

Knowledge is of no value unless you put it into practice.

Everything you want is on the other side of fear

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

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

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

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