There are no bad mistakes in maths, only discoveries.

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

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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

Hard work - a two way street where you get exactly what you put in.
