As I get older, I identify less as my current state and I identify more as a person who transitions through states. My change in perspective has reduced my anxieties and anger significantly. “This too shall pass” vibes. The more my self image is focused on superficial things, the more I will take things personally. What I am angry about tends to be a reflection of myself more than the current state of affairs.
I don’t believe in reincarnation but it is a helpful thought experiment to think about what benefits and drawbacks your particular incarnation of life holds and how those might be different if you were incarnated elsewhere.
