It always seems impossible until it's done.

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

There are no bad mistakes in maths, only discoveries.

Fall down seven times, stand up eight.

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.

Everything you want is on the other side of fear

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

The easiest person to deceive is yourself.

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

He who has begun his task is half-way done. Have the courage to begin!

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Success is not final, failure is not fatal.  It is the courage to continue that counts.

Nobody said it’d be easy, they just promised it would be worth it.

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

Just stick with it, what seems hard now will one day be your warm up.
