I understand that. It's why I held off for so long. I changed my mind a fair bit from when I was your age to now (I'm 21) and now I'm back to what I was wanting to do years ago, just a different version of it. I'm not sure how it works for you, but you could try taking a break for a while to see if anything sounds better. Or try finding a job shadowing thing so you can see if they would be a good fit or not
