You can have results or excuses, not both

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

Skills are built not born.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

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

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. 

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

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

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

Dreams don't work unless you do.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

Tough times never last, but tough people do.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Failure to prepare = preparing to fail
