I think that this is one of the problems many content creators have on Hive as they look at their each and every post payout as an indication of success or failure and often, they do this in comparison to others on the platform

Your actually right because some content creators may seem unhappy If they notice their post is not actually getting the desired reward it deserve when comparing it with others but what I believe is that to build oneself is to continue doing the right thing and at the same time never relent because success or the desired reward will come someday.
