In my years I've learned two secrets to success in life. The first, Do the Work, is pretty well-known. But the second one is maybe more important, and worth doing first:
Figure out when someone else has already done the work for you.
The blockchain's public ledger is pretty amazing for this particular lesson. When I hear that it's hard to find good content on Steem, I feel like those people are failing it, because I've already done the work for them, and so have a bunch of other people, and it's almost right in front of you.
It's true that building your Steem feed from scratch is pretty difficult. Tags are complicated, Trending and New are almost useless, search is really good at finding posts from 2017. I approached it largely from scratch, and it took me three months to build a feed that was consistently providing me with excellent content, and it's work to keep it up as new users arrive and old ones leave. I was prepared to do that because I'd been on a similar platform before and came in prepared.
But here's the thing: you don't have to. I've already done it, and you can just use mine. Steemit doesn't advertise it, and there isn't even a button, but it's possible to get to any user's feed just by adding /feed after their username in the URL. So if you're feeling like you're having a hard time finding good content, I'd suggest just browsing over to https://steemit.com/@tcpolymath/feed and scrolling through that for a while. There's no end of interesting stuff there at any given time, and I have a very wide variety of interests, so it's a pretty good chance you'll find something that appeals to you.
But you don't have to do it with me. Pick any interactive user who has been here a while and look through their feed, you'll find plenty. We're all out there looking for good content and you can take advantage of that very easily. Here are a few extensive ones that I recommend, and if for some reason you need more after that just start clicking on some of the users you see in a bunch of them. You'll have generated your own feed in no time.
Steeming can be a lot easier if you recognize that a lot of the things you're trying to do are already being done by other people, and because it's on the blockchain all of their activity is public. Some things are easier to find than others.
