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

Success can never happen without the journey (struggle).

You're not in competition with anyone but yourself. Outdo your past, not other people.

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

It always seems impossible until it's done.

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

There are no bad mistakes in maths, only discoveries.

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

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

If you fail, next time fail better.

You can have results or excuses, not both

Failure to prepare = preparing to fail

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

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

Dreams don't work unless you do.
