I totally get it.
Example: It took me years to let go of posting on Google+ … I just got too busy for posting somewhere with no engagement. I finally posted a message there saying I’m experimenting with not posting there. I’m glad I let it go.
Another example: I stopped posting to Linkedin Articles, with this final article.
I encourage you to try letting something go, as an experiment, for 1–2 weeks and see how it feels? :)
