I think, therefore I am.

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

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

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

Don’t hang your targets after you’re done shooting.

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

There are no bad mistakes in maths, only discoveries.

Go as far as you can see, when you get there, you’ll be able to see further

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