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

Tomorrow is worth more than yesterday but less than today.

Life is full of opportunities. With every opportunity that is missed, another one is born.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Lose an hour in the morning and you will spend all day looking for it.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

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.

Pure mathematics is in its way, the poetry of logical ideas.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

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

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

Success can never happen without the journey (struggle).
