Making good use of your extra time I see.
Ever since I've focused on engagement my posts have had way more interaction. I can't say that always results in the highest payout, but I really enjoy it when people actually choose to consume the things that I take the time to create.
Some people may be asleep if you always post in the morning. Then by the time they wake up, their feed is full of other new content and they may miss what you posted. Varying when you post can be quite a tactical move.
