Very touching, and all true... I am a perfectionist too and I hear you...
Especially this part of yours: " Every moment we exist, our conditions are somewhat different from any other moment we have ever or will ever exist in and the longer the time exposure to influencing factors, the more they change." sums up everything...
I just wrote a similar post (without copying you haha!!!), asking more or less the same questions (unfortunately not many answers though...) about happiness... I'll be glad if you take a look and tell me what you think: https://steemit.com/life/@meanmommy33/what-is-happiness Until then, upvoted and greetings from Denmark @tarazkp :)
