The first principle is that you must not fool yourself — and you are the easiest person to fool. — RICHARD FEYNMAN

History, you must understand, is not about the past. It’s a lens for understanding the present (that’s why we fight over what gets taught). It’s way of predicting, even determining the future.

As a young basketball player, Bill Bradley would remind himself, “When you are not practicing, remember, someone somewhere is practicing, and when you meet him he will win.

This is what the best journals look like. They aren’t for the reader. They are for the writer. To slow the mind down. To wage peace with oneself.

People turn shit into sugar all the time — shit that’s a lot worse than whatever we’re dealing with. I’m talking physical disabilities, racial discrimination, battles against overwhelmingly superior armies. But those people didn’t quit. They didn’t feel sorry for themselves. They didn’t delude themselves with fantasies about easy solutions. They focused on the one thing that mattered: applying themselves with gusto and creativity.

If we can focus on making clear what parts of our day are within our control and what parts are not, we will not only be happier, we will have a distinct advantage over other people who fail to realize they are fighting an unwinnable battle.

Be the person who surprises others with your genuine interest in them, the respect you extend, and your disregard for unnecessary formalities or status symbols.

Most of us would be seized with fear if our bodies went numb, and would do everything possible to avoid it, yet we take no interest at all in the numbing of our souls. — EPICTETUS

Aspiration leads to success (and adversity). Success creates its own adversity (and, hopefully, new ambitions). And adversity leads to aspiration and more success. It’s an endless loop.

In its own way, the most harmful dragon we chase is the one that makes us think we can change things that are simply not ours to change. That someone decided not to fund your company, this isn’t up to you. But the decision to refine and improve your pitch? That is. That someone stole your idea or got to it first? No. To pivot, improve it, or fight for what’s yours? Yes.

Take inventory for a second. What do you dislike? Whose name fills you with revulsion and rage? Now ask: Have these strong feelings really helped you accomplish anything? Take an even wider inventory. Where has hatred and rage ever really gotten anyone? Especially because almost universally, the traits or behaviors that have pissed us off in other people — their dishonesty, their selfishness, their laziness — are hardly going to work out well for them in the end. Their ego and shortsightedness contains its own punishment. The question we must ask for ourselves is: Are we going to be miserable just because other people are?
