There are no shortcuts to any place worth going.

Procrastination is the thief of time and the enemy of success.

Everything you want is on the other side of fear

There are no bad mistakes in maths, only discoveries.

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

The master has failed more times than the beginner has even tried

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. 

Failure to prepare = preparing to fail

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

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

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

We learn more from failure than we do from success.

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