Hello Entropy, first of all I suggest you to follow @steemitblog and @disconnect and check their blogs. They publish several posts with info about a lot of contests organized by the various communities. Then, you can discover various themes there and join the initiatives they talk about.

If you want to know more, there are two posts I suggest you:

https://steemit.com/hive-188403/@event-horizon/club5050-club75-club100-all-you-need-to-know

to start your adventure in the Steemit clubs, if you want. So, you can use the tags indicated there and obtain a bigger engagement.

If you are a photography or travel interested user, you can check WOX and Travelling Steem community

Good luck for your future here and for life in general. If you want, ask me (if I don't answer, write me on my blog: at the moment, I don't receive all the notifications about engaging).
A big nice day to you! :)
