Why Even Write?

Barely reflected in my use of DW, but I've had a much better time thinking of writing and talking to my friends-- on Discord that's a genre of writing-- as "developing my ideas among supportive people who can help me notice mistakes" and "seeing if anyone vibes with my take". "Persuading everyone that it's okay to believe x" and "persuading everyone to agree" were (are?) exhausting, even though I'm jealous of people who are good at this stuff for real, the people in the Major Leagues of posting takes. It's also hard to measure how much I'm persuading people vs. finding kindred spirits, so it honestly makes me feel worse about whatever I've spun out about.
And why should I adopt a frame that makes "finding kindred spirits" feel cheap, when kindred spirits are hard to find? I want to meet people on my wavelength, and I mean stuff that's less-legible, that doesn't translate into or flow from the kind of group identity we put in bio. A million people can call themselves An X and apparently we work together on some group project, but how do they feel about this one incidental detail? Are they noticing what I'm noticing and feeling kinda similar about it? Unlikely. 
Anyways, sharing a take to a friend like, idk, a writers' group. I'm showing my friend a work in progress; maybe it has some glaring issues, but better to find that out now than to embarrass myself in front of a larger audience, and now I know what to work on. And we can become closer because we shared these work in progress ideas, the kind that are likely to provoke embarrassing interactions w/ randos, and gave each other attention for it.
(Yeah, I'm having a lot of small-scale thoughts lately.)
