My advice...don't start your own business.
It's not for everyone but it can be rewarding. I would say, "Don't open your own restaurant".
The travel is interesting. Some people like it. Others do not. If travel interests you, I agree that traveling the US is great and even driving some long stretches of it. But international travel is really eye-opening and fun. My family and I have been to Mexico, Costa Rica, a bunch of spots in the Caribbean and also Munich, Vienna, Prague, Warsaw, Brataslava, Frankfurt, Croatia, Athens and Santorini. Actually getting where you're going is not glamorous. But being there and meeting people and seeing how others live, their scenery, buildings that might be 800 or 1000 years old, that's amazing. To eat their food, drink their beer and sit and talk with them is really cool. If travel is not your thing, ignore it and focus on what DOES interest you.
