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

There are no bad mistakes in maths, only discoveries.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

Failure to prepare = preparing to fail

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. 

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

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

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

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

Hard work beats talent when talent doesn't work hard.

Procrastination makes easy things hard and hard things harder.

The road to success is like a staircase. If you want to succeed, double your failure rate

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