I can’t recommend a year abroad enough, if it’s accessible to you. Maturity could help, but I think there’s a reason why so many young people travel. It forces you to take steps whether you think you’re ready to or not. You evolve through the good and the bad parts of it. I moved to New Zealand at 20 after living under my mom’s midwestern wing my whole life. I think I would be stagnating if I hadn’t gone through that, though it was absolutely difficult.
