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.
Ray DalioEvolution is the only thing that exists through time. That is true for computers, or people, or a business. We tend to see things in a static way, and so you see what is. Even in looking at ourselves, what we really are is essentially vessels for our DNA that keeps evolving through time. So seeing that and embracing that reality, and thinking of everything as kind of this perpetual motion machine in which you embrace reality - you don't wish it was different. You realize that it's your puzzle to interact with. You interact with it well, you evolve yourself.
