You nailed it pretty much. I make a lot more morey commenting that posting and it takes much less effort and time. Also, another advice is ti follow people that interest you, with same conversation topics and comment on their posts regularly, build a connection and you'll way more upvotes and followers. It's about socializing with fellow Steemians and definitely don't comment on something that doesn't interest you. Steemit is a place to enjoy and earn some cash by doing whay you like.
