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

Success is not final, failure is not fatal.  It is the courage to continue that counts.

If you can understand just one thing thoroughly, then you will understand everything.

99% of failures come from people who have the habit of making excuses.

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. 

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.

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

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

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Try and do one thing each day that you would really rather not do.

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

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

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

We are all maths people : step 1 - do maths and step 2 - be a person.
