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. 

The greatest mistake we make is living in constant fear that we will make one.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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

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

Fall down seven times, stand up eight.

The journey of a thousand miles begins with one step. 

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

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

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

Success is a journey, not a destination.

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

The greatest enemy to human potential is your comfort zone

There are no bad mistakes in maths, only discoveries.

Dreams don't work unless you do.
