Failure is not the opposite of success, it is part of the success.

Skills are built not born.

Hard work beats talent when talent doesn't work hard.

Never underestimate the importance of small steps. small steps = big changes. 

Run in the morning before your body figures out what you're doing

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. 

There are no bad mistakes in maths, only discoveries.

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

We learn more from failure than we do from success.

Knowledge is of no value unless you put it into practice.

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

You can be shown the path, but only you can make the first step.

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

99% of genius comes from hard work, the remaining 1% comes from innate talent

We are all maths people : step 1 - do maths and step 2 - be a person.
