You only have one chip to bet, and it's your life, so you better be sure it's right. It's something intrinsic.
Religion is an attempt to understand the meaning of the universe.
If there is a meaning and purpose to it all, then it would clearly affect what the universe is really like. I find meaning in everything if I am seeing life correctly. If you're willing to sacrifice yourself, you can have a tremendous impact on the world. When you figure out what God wants you to do, go out and do it. The truth is, significance is more than success.
