I want to become a peacekeeper
Why do you want to become a peacekeeper?
I was inspired by watching a lot of programs on TV where volunteers would travel the world and help the more unfortunate.
You should go for it. If you think you're a perfect fit for the job.
I'm unsure on if it's right for me. How do I know if it's right for me?
You never know if something will be right for you unless you give it a shot. It may or may not work out for you but at least you can say that you tried. It's better to try and fail than to just give up.
