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. 

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

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

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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

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

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

Failure to prepare = preparing to fail

Tough times never last, but tough people do.

It doesn’t matter where you start, it matters how you end

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

Knowledge is of no value unless you put it into practice.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

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