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

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

Failure to prepare = preparing to fail

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.

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

There are no bad mistakes in maths, only discoveries.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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

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. 

You cannot escape the responsibility of tomorrow by evading it today

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

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

I can is 100 times more important than IQ.

We learn more from failure than we do from success.

Procrastination makes easy things hard and hard things harder.
