This is a life changing advice..! help?

I would say, go for it,have your overseas experience. It is a great opportunity in life,a chance to meet new people and to gain experience. I don't know in what fied you want to volunteer,but the experience itself it's worth,you will be exposed to another culture and will get a chance to get another perspectivee on life. Many employers value overseas experience,plus it shows that you are not afraid of challanges.Good luck!
