Your attitude is everything. Pick a good one.

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. 

FAIL - First Attempt In Learning

Hard work beats talent when talent doesn't work hard.

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

The wise person knows that no answer is also an answer

Just stick with it, what seems hard now will one day be your warm up.

The journey of a thousand miles begins with one step. 

Failure to prepare = preparing to fail

Do what you have always done and you will always be what you have always been

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

Dreams don't work unless you do.
