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.

The greatest mistake we make is living in constant fear that we will make one.

I think, therefore I am.

I can is 100 times more important than IQ.

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

The journey of a thousand miles begins with one step. 

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

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. 

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

Time is your friend, impulse is your enemy.

There are no bad mistakes in maths, only discoveries.

You cannot escape the responsibility of tomorrow by evading it today

The road to success is like a staircase. If you want to succeed, double your failure rate

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.
