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

There are no shortcuts to any place worth going.

If you fail, next time fail better.

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 journey of a thousand miles begins with one step.

A book a day keeps the stupidity away.

The wise person knows that no answer is also an answer

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

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

He who has begun his task is half-way done. Have the courage to begin!

If you want to succeed, double your failure rate.

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.

Everything you want is on the other side of fear

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