Do you feel like quitting steemit or you feel is better to be less active since all your post hasn’t brought much to you. Do not quit or become less active, just keep the faith, one day your post will also trend on steemit. Do not give up easily, even if you have made quality post and your post didn't get the upvotes it actually deserved, just keep working, Rome was not built in a day. Steemit will surely bless you spend more time on it, just keep doing what you are doing and don't be discouraged. I’m confident that those of us who are yet to benefit from steemit, our time will surely come.
Steemit is not all about quality post, though it’s cool to always make quality post, but personally I have seen some less quality post making it to the trending page while some quality post end up as trash. When is your time, nothing can stop you, thus I will advise you keep trying, don’t give up, sooner or later, your time shall come and your post shall trend.
