“People say that you should not micro-optimize. But if what you love is micro-optimization… that's what you should do.”

“But why should you care what people will say? All you have to do is please yourself.”

“As someone pointed out, you could have an attribute that says 'optimize the heck out of this routine', and your definition of heck would be a parameter to the optimizer.”

“Love what you do and do what you love. Don't listen to anyone else who tells you not to do it. You do what you want, what you love. Imagination should be the center of your life.”

“In science if you know what you are doing you should not be doing it.
In engineering if you do not know what you are doing you should not be doing it.”

“People say you should give until it hurts. I say you should give until it stops hurting. Know what I mean?”

“And today, I want to share with you my vision of what our future can be. I want the Cuban people -- especially the young people -- to understand why I believe that you should look to the future with hope; not the false promise which insists that things are better than they really are, or the blind optimism that says all your problems can go away tomorrow. Hope that is rooted in the future that you can choose and that you can shape, and that you can build for your country.”

“This is what you should know about losing someone you love. They do not travel alone. You go with them.”

“To determine whether or not you have the ingredients to be charismatic, answer the following questions: What are your real feelings about who you are? What do you believe in? Do you have goals or a mission in life? Do you project optimism? Do others turn to you for leadership? Non-charismatic people spend their lives auditioning for others and hoping they'll be accepted. Charismatic people don't doubt their ability to add value to a situation, so they move forward with their mission.”

“Possibly, the most common error of a smart engineer is to optimize something that should not exist.”
