There are no bad mistakes in maths, only discoveries.

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

The journey of a thousand miles begins with one step. 

99% of genius comes from hard work, the remaining 1% comes from innate talent

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

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

The temptation to quit will be the greatest when you are about to succeed

The bad news is time flies, the good new is that you're the pilot.

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 can is 100 times more important than IQ.

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

Failure to prepare = preparing to fail

Never underestimate the importance of small steps. small steps = big changes. 

If you really want something you’ll find a way. If you don’t you’ll find an excuse.
