I agree with all of these my dude. It was funny because as I was reading your first few I thought a few of my own, only to find out you had them later on in your post lol.
My biggest problem is being consistent when posting. I'll get a decent followering week to week then I'll be absent for a week (because life), then get back on to have a good post get minimal upvotes.
Your last point was the biggest. Just have fun with steemit. Use it as a learning tool, a blogging tool, or anything in-between. The uses of this platform are virtually endless. I even follow a few pages that post only memes and I love it hahaha.
Excellent post for beginners! resteemed mate
