Frustrating, for sure... but you just have to keep plugging away at it.
I think it was my 6th post here... it was about having gratitude, and it had well written thoughts and pretty pictures (all my own), took a couple of hours to put together... and it even got 19 upvotes and STILL earned a bit fat $0.00! And I certainly had dozens of posts that earned less than $1.00 and I did my best on all of them...
