"I" not them. Be the best version of you.

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

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

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. 

Tough times never last, but tough people do.

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

Failure is NOT your destiny. Failure is the key to success.

Dreams don't work unless you do.
