Hope might be a good breakfast, but it makes a very poor dinner

I can is 100 times more important than IQ.

We learn more from failure than we do from success.

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

Time is your friend, impulse is your enemy.

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

Tough times never last, but tough people do.

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

The journey of a thousand miles begins with one step. 

You cannot escape the responsibility of tomorrow by evading it today

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

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

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.
