Hi, While there is a wide array of options in engineering to choose from, I can understand why it can be sometimes confusing and overwhelming. The good news is you're getting a head start on figuring out what you want to do. The best way to narrow down your interest and passion is by attending some of the events where engineers create things like maker fairs , or listen to Ted talks online about latest engineering feats, or attend devoxxforkids and other intro to tech courses where you get to try your hand at chip design to game design to drones and everything in between. Try and read an article about a different discipline in engineering every day. See what ends up sticking to you the most. You've got time to figure out what ends up being a fleeting interest vs what ends up being a life time passion.
