Hi @t-o-m-a, just saw your post by accident.
I personally think the introduce yourself post would help a lot. Your writing skills will make you successful anyway, but the introduceyourself post will put you in the spotlight a lot quicker. You'll get a lot of comments, some spammy, some genuine, making it easier connect to people who've been on Steemit longer. Definitely check out discord as well. Btw, all the proposed topics sound interesting, so I'm following 👍
