The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

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

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

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

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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

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

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

The easiest person to deceive is yourself.

Failure is not the opposite of success, it is part of the success.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

The master has failed more times than the beginner has even tried

The greatest mistake we make is living in constant fear that we will make one.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.
