As Harvard developmental psychologist Robert Kegan, who has studied Bridgewater, says, in most work places everyone is working two jobs. The first is whatever their actual job is; the second consists of managing others' impressions of them, especially by hiding weaknesses and inadequacies - which is an enormous waste of energy.

The expression I use: Pain + Reality = Progress. Whenever I would have a painful mistake, I started to view that as puzzles that would give me gems if I could solve the puzzle. So, it made me thoughtful - what should I do differently next time? That was the puzzle. And the gem was some principle for handling the same thing when it came along again, and then I would write it down. And by writing it down and referring to it, and also being able to show it to other people so that we could agree that that was a good way of handling that thing - that was very, very powerful.

I also believe that everyone needs to think independently and make their own decisions on what makes the most sense.

For me, the best things in life - meaningful work, meaningful relationships, interesting experiences, good food, sleep, music, ideas, sex, and other basic needs and pleasures - are not, past a certain point, materially improved upon by having a lot of money.

When there is pain, the animal instinct is 'fight or flight' (i.e., to either strike back or run away) - reflect instead. When you can calm yourself down, thinking about the dilemma that is causing you pain will bring you to a higher level and enlighten you, leading to progress.

The pain of problems is a call to find solutions rather than a reason for unhappiness and inaction, so it's silly, pointless, and harmful to be upset at the problems and choices that come at you (though it’s understandable).

People who worry about looking good typically hide what they don't know and hide their weaknesses, so they never learn how to properly deal with them and these weaknesses remain impediments in the future.
