one of the most insightful things I read recently, is that the brain is essentially always trying to get back to 0. To neutral. Framing this around wins and losses is like this:
Pleasure will take you high, but you have to back to neutral. Less pleasurable experiences will take you lower, but you have to go back to neutral.
it's how you deal with and enjoy both.
and if you can reframe wins and losses as just different life experiences, it smoothes all that out. Sometimes in one day, you can go through so many mini wins and losses, but it's navigating that that matters.
