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

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

You're not in competition with anyone but yourself. Outdo your past, not other people.

Your attitude is everything. Pick a good one.

Go as far as you can see, when you get there, you’ll be able to see further

Instead of finding reasons why you can't, find reasons why you can.

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

If you want to succeed, double your failure rate.

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

Mistakes have the power to turn you into something better than you were before.

It always seems impossible until it's done.

If you can understand just one thing thoroughly, then you will understand everything.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

The easiest person to deceive is yourself.
