Keep the dream alive

My name is Khellia. I am 17 years old and live in Sweden.
I think my biggest dream is to help people who are suffering. I want to work for/in the U.N. but I have heard that it is very difficult to get in there (*u could also say: it is very difficult to get a job there). I am not here to tell you all of my dreams because that would take the whole day before I'm done. Instead, I just want to say to all you guys to keep dreaming and to fight for your dreams. Nothing is impossible as long as you want it (* u could also say: as long as you want it bad enough). And you know that if you give up on your dreams it is like dying so don't do that.
Have a good day!
