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. 

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

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

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.

Don’t be afraid to work hard and find out how good you can really be.

I have not failed, I've just found 10,000 ways that won't work.

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

Don’t hang your targets after you’re done shooting.

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

MATHS = Mistakes Allow Thinking To Happen

Procrastination makes easy things hard and hard things harder.

It is never too late to turn an unproductive day into a productive one.

Your attitude is everything. Pick a good one.

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

The wise person knows that no answer is also an answer
