You're not in competition with anyone but yourself. Outdo your past, not other people.

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

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

Patience is when you’re supposed to get mad, but you choose to understand

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

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

You can hire a tutor but you can't hire someone to practice for you.

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.

If you fail, next time fail better.

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

Skills are built not born.

Don’t be afraid to work hard and find out how good you can really be.

Success is the sum of small repeated efforts, day in and day out.

I think, therefore I am.
