Hi, one idea for making a compelling presentation is by watching your body language, here's a link to a TedTalks by Amy Cuddy. I've coached a competitive robotics club for kids who often must present their projects before judges, her ideas really help them with confident speaking/presenting. The first time they tried "getting big" before a competition, they came home with a 2nd place in our state for project presentation.
Also, one interesting tidbit I discovered not long after my first post a few weeks ago, is after the first day (or two?) you can not edit or delete your posts in Steemit. At all. This was a surprise to me and possibly many other bloggers/writers who join Steemit. Now you have to really push for high quality the first time around :)
