Should I keep studying or drop everything?

Hello, Murakami san. My name is Camila and I'm 22 years old. During the past 5 years I've been studying, doing research, being involved in student organizations, and just about everything a med student would do. And even though I really enjoy what I'm doing I often resent the fact that I've never been able to go out into the world. I often dream of visiting places in Europe or Asia and having an adventure. With every year that passes I get more afraid of never traveling because I will always be busy. Even though I love medicine and where I am in life, I constantly find myself dreaming of dropping everything and leaving for a while. I just want to know if I've been wasting my youth. Is it foolish to spend what could be the best years of my life studying? Or should I stay where I am, content with what I have and travel when I'm older?

Dear Camila,

You are 22 years old. You have plenty of time ahead of you, plenty of possibilities ahead of you. I am 66 years old now, and I feel the same way. I feel I will be able to do so many things if I want to. So, don’t worry. You will have a fair chance some time soon. Make your plan and wait.
