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.

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

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

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

You cannot escape the responsibility of tomorrow by evading it today

The power of reflection is the most powerful skill you’ll learn.

We learn more from failure than we do from success.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Time is your friend, impulse is your enemy.

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

I can is 100 times more important than IQ.

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

Try and do one thing each day that you would really rather not do.
