The journey of a thousand miles begins with one step. 

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

Don’t hang your targets after you’re done shooting.

Instead of finding reasons why you can't, find reasons why you can.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

A book a day keeps the stupidity away.

We learn more from failure than we do from success.

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

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

It always seems impossible until it's done.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

I think, therefore I am.

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