To unfollow or not unfollow that's the question. I've noticed that they're people on social media who follow you but don't give a rat's behind about your work and visa-versa. It's kinda like having or needing health or car insurance. You may need it now, but if you're in a bind then it comes in handy. Could that be said for your followers? Or non followers?
I used to be devastated if someone unfollowed me, but now I realize it's NOT personal so relax. Chill out. Some people are only meant to be in our lives for a short period of time. Besides, If they never interact with you or support you then good riddance. Move on to make room for your supporters and people who can actually get you somewhere.
