I think we should always strive to be our best selves and fuck what other ppl think.
I tend to stick with models closer to 'true self' rather than 'best self', since the latter can easily just become about pushing towards a construct ideal that isn't really what we're capable of or otherwise meant to do.
For example, someone in a Wheelchair might make for a terrible Basketball player, but then they find Wheelchair Basketball:
Thinking smarter rather than harder's the path to take.
Nobody's perfect, and even if some of us could be, somebody would always take issue with some stupid thing.
Why they'd take issue with it could be enlightening to what's otherwise wrong with it, and rather than rebuking them their insight could at the very least educate as to why others might make certain mistakes.
It's through others, even when they're insulting us, that we can see ourselves, but we have to see who those 'others' are to factor out the bias as best we can for whatever's left to the message that has utility.
If we can go to bed every night mostly satisfied with our own standards and the best efforts we've put in to meet them, then that's all anybody can do, right?
They can attempt to reshape their standards, much like the path of temple monks.
