I think different things work well for different people, or to use the familar - different strokes for different folks.

I personally have limited myself to just a few posts trying to focus on what I feel will at least get read by some people. In other words, I probably have over researched, over thunk and spent way more time than I probably should have.

In term of rewards I feel I have been rewarded "fairly" over all, however some posts I thought would do really well bombed and ones I thought "meh" did pretty well.

It is a little bit of gamble right now on Steemit, with several factors, I think at first most of us should just focus on writing what we enjoy writing about and building up an audience for it, than later on looking at the rewards and figuring out if it is worth the time or not.
