Am I too ambitious for wanting to travel young?

I’m from the UK and I turn 18 in just over 2 years which is also when I will finish college and I want to take a gap year to travel. A couple of friends and I have said that we will all go somewhere in Europe during that time but I want to travel further abroad. I plan on working until I turn 18 and saving up so that I can travel but I don’t know if I am getting my hopes up too high about this whole thing. I want to travel to the US for a little while when I’m 18, but I don’t know how my parents would feel and if I would be able to afford it or be experienced enough to stay somewhere overseas. Is it worth travelling as soon as possible, or I wait a few more years before considering?
