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

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

Go as far as you can see, when you get there, you’ll be able to see further

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. 

It is never too late to become what you might have been

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

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

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

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

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

You can have results or excuses, not both

Failure to prepare = preparing to fail

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

A book a day keeps the stupidity away.

Time is your friend, impulse is your enemy.
