Skills are built not born.

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

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

You cannot escape the responsibility of tomorrow by evading it today

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

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

Hard work beats talent when talent doesn't work hard.

Just stick with it, what seems hard now will one day be your warm up.

Everything you want is on the other side of fear

There are no bad mistakes in maths, only discoveries.

Failure to prepare = preparing to fail

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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.

We learn more from failure than we do from success.

The master has failed more times than the beginner has even tried
