lack of motivation: "why interacting if I don't get any upvotes"
jealousy: "look at this shitty post, and how it made $20/$40/$whatever_huge_amount, and I make nothing"
bitterness: "it's all about the whales, they are controlling the game and I'm just a minnow"

Been there, done that, considered quitting, engaged the community got disappointed with the community, thought of quitting, focused on the good, got inspired to write again, experienced writers block, just read a lot, did not post a lot, eventually got my groove back.

Very sound advice on not focus on what others are earning, their SP and go with the good and your growth.
