a fun and weird thing i learned here on steemit is that you that you have no idea which of your posts may earn much and which less. At first i remember i was thinking what to write, what they wanna read, WOW this might be my best post it will earn a lot. That wasn't the case :P the ones i believed that would fail earned more and i believe you may have realize it too by now, so just post whatever you like :P
