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

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

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

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

Failure is NOT your destiny. Failure is the key to success.

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

Everything that happens was once a dream.

Life is full of opportunities. With every opportunity that is missed, another one is born.

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

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

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

I think, therefore I am.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.
