When you make a mistake, take another chance. Only when you choose not to do so do you fail.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Don't fear failure, fear being in the same exact same place next year as you are now.

Success can never happen without the journey (struggle).

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

Tomorrow is worth more than yesterday but less than today.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

It is never too late to turn an unproductive day into a productive one.

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

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. 

Run in the morning before your body figures out what you're doing

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

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

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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