I have my EMT cert, but I honestly didn't get it planning to become an EMT, I just wanted the experience. But I lllooooved the class, it was soooo much fun.
I might suggest to practice EMT-ing while you figure out what you want to do next. See how you like it and try out some different things to see what you like best.
My ultimate goal is to be a peds GI doc, but I'll never regret getting that EMT cert

Good luck, dear!
