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. 

Tomorrow is worth more than yesterday but less than today.

Your attitude is everything. Pick a good one.

It doesn’t matter where you start, it matters how you end

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

Pure mathematics is in its way, the poetry of logical ideas.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

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

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

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.

In order to become better than anybody else you must first become better than yourself.

Tough times never last, but tough people do.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Procrastination is the thief of time and the enemy of success.
