For me, posting is a way to slow down.
By seeing every square on my feed, and every single post I’ve made in the past, I know I’ve built a road of some sort for myself.
I can see how I’ve changed as a designer, artist, and human being.
I post without any regard for number of likes or who likes what post or how many followers—I do this for the commitment to me as an artist.
Now, why you should start posting is because I think you’ll find the process liberating, instead of the total nightmare you make it out to be in your head.
Nobody’s watching.
If you have something to contribute, post it.
