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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Instead of finding reasons why you can't, find reasons why you can.

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

Never underestimate the importance of small steps. small steps = big changes. 

There are no bad mistakes in maths, only discoveries.

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. 

The temptation to quit will be the greatest when you are about to succeed

Don't fear failure, fear being in the same exact same place next year as you are now.

The journey of a thousand miles begins with one step.

You can have results or excuses, not both

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

Tough times never last, but tough people do.

The greatest enemy to human potential is your comfort zone

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