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

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

The bad news is time flies, the good new is that you're the pilot.

I can is 100 times more important than IQ.

You can hire a tutor but you can't hire someone to practice for you.

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

There are no shortcuts to any place worth going.

The journey of a thousand miles begins with one step.

There are no bad mistakes in maths, only discoveries.

Pure mathematics is in its way, the poetry of logical ideas.

It doesn’t matter where you start, it matters how you end

Run in the morning before your body figures out what you're doing

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

No one starts out on top. You have to work your way up.

The temptation to quit will be the greatest when you are about to succeed
