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

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

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

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

Success is the sum of small repeated efforts, day in and day out.

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

He who has begun his task is half-way done. Have the courage to begin!

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

Procrastination makes easy things hard and hard things harder.

Lose an hour in the morning and you will spend all day looking for it.

I have not failed, I've just found 10,000 ways that won't work.

The bad news is time flies, the good new is that you're the pilot.

It is never too late to turn an unproductive day into a productive one.

Success is a journey, not a destination.

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