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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

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

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

Start, struggle, fail, fix and learn. Repeat.

Your attitude is everything. Pick a good one.

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

No one starts out on top. You have to work your way up.

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

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

We learn more from failure than we do from success.

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

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

Tough times never last, but tough people do.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.
