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

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

Lose an hour in the morning and you will spend all day looking for it.

Mistakes have the power to turn you into something better than you were before.

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

There are no bad mistakes in maths, only discoveries.

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

Don’t practice until you get it right, practice until you can’t get it wrong.

Life is full of opportunities. With every opportunity that is missed, another one is born.

Don’t hang your targets after you’re done shooting.

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. 

I think, therefore I am.

The journey of a thousand miles begins with one step. 

Everything that happens was once a dream.

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