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

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Time is your friend, impulse is your enemy.

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.

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

There are no bad mistakes in maths, only discoveries.

It always seems impossible until it's done.

A book a day keeps the stupidity away.

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

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

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

It doesn’t matter where you start, it matters how you end

Don't fear failure, fear being in the same exact same place next year as you are now.

If you want to succeed, double your failure rate.

Success can never happen without the journey (struggle).
