"Happy is a yuppie word."
I'm looking for soming a lot deeper than happy. I agree with vikas soni that you won't find happyness, or by any means something deeper in yourself. I don't believe you'll find it even in another person, or two, or three. I agree with the means of vikas soni, and personally I'm challanged by his honestly (which I greatly appreciate), but the ends I disagree with.
"If I find in myself a desire which no experience in this world can satisfy, the most probable explanation is that I was made for another world."
An honest search for Truth has lead me to God and His Son Christ. Having a Home somewhere that isn't here gives you freedom: you don't have to worry about anything in this life, and living for something Bigger than yourself gives you a reason to be here. But certainly Christ teaches that we are to help the hungry, the poor, and deserted...and finding joy in helping them I've decided to become a doctor so I can find those people and help them. Maybe I'll save lives...but I hope to save more than that. I'm spending this summer in a medical clinic in Ghana that serves the public for free, it's in the Village of Hope. That's what gives me Joy, in a nutshell: God and serving others for Him.
