Let's be honest: most of the crappy posts earn nothing, but yes, when one hits the jackpot, that's annoying! Yes, I was pissed off about it at the beginning. But you just need to keep positive, forget and forgive the crappy posts, and concentrate on your own stuff, and make it as good as you possibly can. Someone was saying that Steem is a bit like a lottery and it's true in some sense. However, the more your account grow and your subscribers grow, the less your success has to do with luck.
But it's demotivating to see all your effort and hardwork go in vain when someone just writes a few lines and hit a jackpot. You're right though. I gotta work harder.
Yes, I know how you feel.
Thanks.
