Don't fear failure, fear being in the same exact same place next year as you are now.

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

The power of reflection is the most powerful skill you’ll learn.

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

Everything you want is on the other side of fear

There are no shortcuts to any place worth going.

There are no bad mistakes in maths, only discoveries.

The greatest enemy to human potential is your comfort zone

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

If you fail, next time fail better.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

The journey of a thousand miles begins with one step.
