It is never too late to become what you might have been

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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

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

Success is a journey, not a destination.

There are no bad mistakes in maths, only discoveries.

Everything that happens was once a dream.

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

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

Dreams don't work unless you do.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

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

It always seems impossible until it's done.

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