HI paws202,
and welcome
I agree with Perna. Starting college later in your life is definitely harder. Some colleges and universities allow you take different subjects the first year so that you can choose one of them if you are not yet sure, what you want to do. Travelling is a wonderful idea, however, it is not cheap and building on some skills is really important. There are some very good opportunities for travelling joint with volunteering which can be done during summers between college years, and they often are in very interesting and cultural places.
also you can always have a gap year somewhere in between, which can allow you to expand your horizons through travelling

However I would also suggest stick with education, as it is not like riding a bike. Once a lot of time passes it is quite hard to get the hang of it again.
