The easiest person to deceive is yourself.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

Failure to prepare = preparing to fail

We learn more from failure than we do from success.

You can have results or excuses, not both

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Your attitude is everything. Pick a good one.

The road to success is like a staircase. If you want to succeed, double your failure rate

Tomorrow is worth more than yesterday but less than today.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

99% of failures come from people who have the habit of making excuses.

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

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. 

Procrastination makes easy things hard and hard things harder.
