Yes it is okay to be proud of yourself nowadays. I am also a woman who likes sci-fi. I just watched Stranger Things on Nextflix, though it's a bit more horror than sci-fi I suppose. I think videography should do very well on Steemit. You could even start by making this post into a video and posting it, too. Then we could hear some of your music, even. You're lucky to have proficiency in so many media!
