One reason we resist change is that keeping things the way they are requires almost no effort. This helps explain why we get complacent. It takes a lot of effort to build momentum but far less to maintain it. Once something becomes “good enough,” we can stop the effort and still get decent results. The inertia default leverages our desire to stay in our comfort zone, relying on old techniques or standards even when they’re no longer optimal.

Having made the decision, do not revise it unless some new fact comes to your knowledge. Nothing is so exhausting as indecision, and nothing is so futile.

It is always thus, impelled by a state of mind which is destined not to last, that we make our irrevocable decisions.

Decisions are always made with insufficient information. If you really knew what was going on, the decision would make itself.

Once I make up my mind, I'm full of indecision.

Without conscious and deliberate effort, inertia always wins

If you’ve never changed your mind about something, pinch yourself; you may be dead.

Sometimes I worry we've already made our decisions and have no hope of undoing them.

For the first ten years or so, you would always question whether the decisions were right or wrong, but you have to learn to put things behind you once a decision is made. You can't be wishy-washy about it.

Anytime you have difficulty making an important decision, you can be sure that it’s the result of being unclear about your values.

It's hard to change a coach's mind once he makes it up a certain way.

Sometimes you have to take a hard decision and when you take such a decision, you have to stand by it. It’s not everybody who sees what you are seeing.

I’ve found that if I can't come up with even an inkling of how my mind might be changed, then I'm not really thinking at all; I'm just set on holding on to my current beliefs.
