Congratulations on reaching this incredible place so early in life! I'm massively impressed! I would like to offer a thought that may (or may not) be helpful? I've faced many a difficult decision in my decades on the planet and one thing that I've learned is this: If you're really not sure what to do, don't do anything you can't easily UNDO until you are as certain as you can be about your decision.

In the meantime, dig around and get some ideas for that next big Adventure!

Good luck to you; I'm sure you'll do great in life, whatever you choose!
