Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Tough times never last, but tough people do.

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

I can is 100 times more important than IQ.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

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

You cannot escape the responsibility of tomorrow by evading it today

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

It is never too late to turn an unproductive day into a productive one.

There are no bad mistakes in maths, only discoveries.

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

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.

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

We learn more from failure than we do from success.
