In all seriousness though, while boobs are insanely awesome, what drives me to continue life is God. Which seems like a contradiction at times because you wouldn't really know I'm a Christian based on my life. I have certain convictions like abstaining from sex and drugs, and I don't really swear all that much, so I am a somewhat "moral person"—I just don't really serve God and others in the way that Christ commanded, which makes me a king-sized turd.
I don't necessarily believe that one has to entirely devote his or her life to the cause of witnessing to others and spreading God's love. I believe that God gave this earth for people to enjoy, where all too often the stricter, more extreme Christians would have you think that the beauty in this life means nothing and all that matters is spreading the gospel to help save others for the glorious afterlife. While I believe witnessing to be important and it is something Jesus commanded, I think some people take it to extremes. And while this earth's beauty will pale in comparison to the new earth, there's still so much here to be amazed by and to take in and enjoy. I can worship God without having to spell out His Son's name or wave a Jesus flag in everything I do.
But God is the source of all beauty and creativity. All love and all understanding. Without God, there would be nothing. As such, without God, I become deeply despondent. I'll be honest: because of my sin nature, I quite often stray from God and choose to do my own thing. I go days without uttering so much as a prayer. I enjoy life—in my own secluded sort of way. I'm an entertainment and art junkie, so I'll spend a lot of time playing video games or watching movies and anime. I see a select few friends when they're available and I enjoy that social interaction. I enjoy greasy, fatty foods.
Go for a swim or a bike ride weather permitting. I don't have a terribly varied field of activities, but what I do, I enjoy fully, and I mix it up amongst those things.
But that all gets wearisome after some time. It's a source of happiness, but not an ultimate source. Those things—even close friends and family—cannot take away depression. They can sometimes help alleviate the pain in darker times, but I'm fully convinced based on the things I've experienced in my life that only God can offer any kind of true, lasting satisfaction.
Whenever I get into my really apathetic moods which last for months, I tend to revel in all kinds of sin. Not so much anymore as I've grown a bit in character, but basically "anything goes." It was always those times—at my weakest—where I threw out what was moral and would enjoy the company of women. It would be fun, for sure, but it didn't help me get out of that misery—it only made it worse. Sexual activities just weren't meant to be experienced in such a fleeting way or with people who aren't congruent with you (there was a girl who was really neat and was mad about me, and I think we would've been a good couple for a while, but somewhere down the line I guarantee there would have been troubles based on our differences and worldviews).
I dunno... I might be talking out my ass at this point and not making a whole lotta sense, but when something as fantastic as being close to a woman, emotionally and physically, doesn't help you out of that pit, it makes you think, "What can?" And from my experience, the only thing that brings me out of that despair is God.
