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

Hard work - a two way street where you get exactly what you put in.

Everything that happens was once a dream.

The road to success is like a staircase. If you want to succeed, double your failure rate

Dreams don't work unless you do.

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

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

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

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

I have not failed, I've just found 10,000 ways that won't work.

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

Your attitude is everything. Pick a good one.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

There are no bad mistakes in maths, only discoveries.

You can hire a tutor but you can't hire someone to practice for you.
