Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

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

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

There is no elevator to success, you have to take the stairs.

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

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

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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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

Run in the morning before your body figures out what you're doing

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

A book a day keeps the stupidity away.

Procrastination makes easy things hard and hard things harder.
