Ray Dalio says in his book Principles, “Don’t tolerate the problems.” He’s talking about how he plans his goals; his method involves identifying the goal, then the problems that are in the way of getting there. Unfortunately, this means people sometimes. How often has an experience with a person been enriching and rewarding, helping to achieve your goals versus the opposite?
Having these goals in the first place is what sets up the contrast. What you would once tolerate because there was simply no reason not to, now is nothing less than an existential threat to a better version of yourself. This cannot be tolerated.
