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

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

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.

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

You can have results or excuses, not both

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

Failure is not the opposite of success, it is part of the success.

You cannot escape the responsibility of tomorrow by evading it today

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

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

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

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

Our fixed mindset builds our cage, fear keeps us in it.

Success can never happen without the journey (struggle).
