Living Like It's Your Last Day

Alright, So I've been thinking about this a lot.... What does it mean. I kinda take from it that it means be super outgoing. But the problem with that is that on July 29th, I'm going to Young Life Camp in New York and oh my goodness! There is so much to do! And it's scary things. I used to be an adrenalin junkie, but now, I'm a scaredy-cat! I hate it. But I'm not sure how to overcome a fear. I want to before I die, but what if the thing I do kills me. haha. Idk, Just a thought.
