Life is NOT pointless! Of course, I have my religion and it gives me something to hold to, go by, and look forward to in the next life. But other people might not have what I have.
I have a family, a job, my school, and something to do. There are people that love me, count on me, trust me, and that would be sad if I was to go. I have made a difference in someone's life, and while I've never been famous and probably never will be, my life is NOT pointless.
Be busy, be involved, be engaged, stand for something, be someone's hero . . . and life won't ever be pointless.
