Being paid for posts makes it really hard to not access the value of the post, and then even our own self value, based on the payout. It's taken me the best part of a year to mostly not do that, and I have to admit I still do it a bit.
Now most of my posts are earning 10x what they were earning a few months ago, but I have to admit if I did a post now that only earned $4 I'd probably think I was a worthless loser and start wondering how to buy upvotes.
Back in my days of posting on fakebook I used to assess the value of my posts by how many unfollows I got (I didn't get any likes)
