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. 

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

Do what you have always done and you will always be what you have always been

"I" not them. Be the best version of you.

Run in the morning before your body figures out what you're doing

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

Success is a journey, not a destination.

We learn more from failure than we do from success.

The bad news is time flies, the good new is that you're the pilot.

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

Your limitation - its only your imagination.

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

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.
