Keep away from those who try to belittle your ambitions. Small people do that, but great people make you believe that you too can become great.

Mark Twain

We find comfort among those who agree with us, and growth among those who don’t.

Franka. Clark

Be self aware, rather than a repetitious robot

Bruce Lee

Watch your thoughts; they become words. Watch your words; they become actions. Watch your actions; they become habits. Watch your habits; they become character. Watch your character; it becomes your destiny.

Lao Tzu

Improvise, Adapt, Overcome

Clint Eastwood

Try to learn something about everything and everything about something.

Thomas Henry Huxley

Once you have something that grows faster than education grows, you’re always going to get a pop culture.

Alan Kay

Only those who will risk going too far can possibly find out how far one can go.

T. S. Eliot

The problem, often not discovered until late in life, is that when you look for things in life like love, meaning, motivation, it implies they are sitting behind a tree or under a rock. The most successful people in life recognize, that in life they create their own love, they manufacture their own meaning, they generate their own motivation.
For me, I am driven by two main philosophies, know more today about the world than I knew yesterday. And lessen the suffering of others. You’d be surprised how far that gets you.

Neil deGrasse Tyson
