If you have more than three priorities, you don’t have any. - Benjamin P. Hardy

To quote Adam Grant in Think Again: To unlock the joy of being wrong, we need to detach. I’ve learned that two kinds of detachment are especially useful: detaching your present from your past and detaching your opinions from your identity . . . My past self was Mr. Facts — I was too fixated on knowing. Now I’m more interested in finding out what I don’t know. As Bridgewater founder, Ray Dalio told me, “If you don’t look back at yourself and think, ‘Wow, how stupid I was a year ago,’ then you must not have learned much in the past year.”36

Knowing the why is the deepest and most powerful form of knowledge because the why is always the driver of the what and how. When you understand why the stock market goes up and down, making informed decisions about investing becomes easier. When you understand why someone does what they do, their actions and behaviors make a lot more sense.

There is nothing quite so useless, as doing with great efficiency, something that should not be done at all.
