Tomorrow is worth more than yesterday but less than today.

There are no bad mistakes in maths, only discoveries.

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. 

We learn more from failure than we do from success.

I think, therefore I am.

The journey of a thousand miles begins with one step.

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

Success is a journey, not a destination.

Fall down seven times, stand up eight.

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

Tough times never last, but tough people do.

Time is your friend, impulse is your enemy.

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

Hard work - a two way street where you get exactly what you put in.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.
