Plenty of good posts don't get the rewards they deserve whilst others get auto-votes regardless of the quality. That is a fact of life here, but not a reason to give up hope. At least peakd gives you the option to check for more recent posts by that person so they could still get something if they stay active. A lot of my early posts made nothing, but I was having fun anyway.
I manage to keep my enthusiasm up, but I get that it can feel like a slog for others. We each have to do what we can to improve that.
