Men give me credit for some genius. All the genius I have lies in this: When I have a subject in hand, I study it profoundly. Day and night it is before me. I explore it in all its bearings. My mind becomes pervaded with it. Then the effort which I have made is what people are pleased to call the fruit of genius. It is the fruit of labor and thought.

The difference between genius and stupidity is; genius has its limits.

The problem with smart people is that they like to be right and sometimes will defend ideas to the death rather than admit they’re wrong. This is bad. Worse, if they got away with it when they were young (say, because they were smarter than their parents, their friends, and their parent’s friends) they’ve probably built an ego around being right, and will therefore defend their perfect record of invented righteousness to the death. Smart people often fall into the trap of preferring to be right even if it’s based in delusion, or results in them, or their loved ones, becoming miserable. (Somewhere in your town there is a row of graves at the cemetery, called smartypants lane, filled with people who were buried at poorly attended funerals, whose headstones say “Well, at least I was right.”)

Until they come face to face with someone who is tenacious enough to dissect their logic, and resilient enough to endure the thinly veiled intellectual abuse they dish out during debate (e.g. “You don’t really think that do you?” or “Well if you knew the <insert obscure reference here> rule/law/corollary you wouldn’t say such things”), they’re never forced to question their ability to defend bad ideas. Opportunities for this are rare: a new boss, a new co-worker, a new spouse. But if their obsessiveness about being right is strong enough, they’ll reject those people out of hand before they question their own biases and self-manipulations. It can be easier for smart people who have a habit of defending bad ideas to change jobs, spouses, or cities rather than honestly examine what is at the core of their psyche (and often, their misery).

A lie can travel halfway around the world while the truth is putting on its shoes.

Hain't we got all the fools in town on our side? And hain't that a big enough majority in any town?

Force and mind are opposites; morality ends where a gun begins.

An honest man is one who knows that he can't consume more than he has produced.

I would rather be ashes than dust! I would rather that my spark should burn out in a brilliant blaze than it should be stifled by dry-rot. I would rather be a superb meteor, every atom of me in magnificent glow, than a sleepy and permanent planet. The proper function of man is to live, not to exist. I shall not waste my days in trying to prolong them. I shall use my time.

Genius is made, not born.

I have learned this at least by my experiment: that if one advances confidently in the direction of his dreams, and endeavours to live the life which he has imagined, he will meet with a success unexpected in common hours.
