I have the ability to teach - even remotely. I enjoy that. I also love to write - always have. I love that Steem means I don't have to have just one niche (that's why previous attempts to blog failed - plus I'm terrible at marketing!)
I think everyone can produce high-quality content - if they have the time - and if they can just slow down a little to think their way through it. Of course, length isn't everything - though it can help. Your post that I just upvoted/commented on (about that line in Prisoner) is quite powerful in its own little way.
I was actually criticized over at Whaleshares for my lengthy posts! Apparently, they're more interested in soundbites. Of course, now that their hard forks have settled down a bit and I can post as I like, I've continued my stories there - with the blessings of several witnesses. :-)
