Contribution to a Goal

When I turned 16, everyone told me that I should give blood because I'm O+ and it is always needed, but I always chickened out. When I turned 17, one friend of mine is the same blood type as me and she came to me and told me that if she does it, I have to do it. Since then I have loved giving blood. I have a goal in life to save and help lives. I go on mission trips every year to help change lives and to me giving blood is just another small contribution to that goal.
