We all have two lives. The second begins when we realise we only have one. 

Your limitation - its only your imagination.

There are no bad mistakes in maths, only discoveries.

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

You can have results or excuses, not both

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

Do what you have always done and you will always be what you have always been

Success is the sum of small repeated efforts, day in and day out.

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

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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

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

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

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

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