how vs why

I'm moving away from the hows in life and focusing more on the whys. We always think about the hows: how to get a mate, how to get food, how to get sex, how to get whatever.... but why? We pretty much ignore it. How leaves you with a lot more black and white, cut and dry, solutions and answers. Why leaves you open and alone in the land of the gray. And for some reason, right now, the hows: the answers and solutions aren't that much fun. I'm really enjoying being lost in the fog of the whys. Why are we designed to need other people? Why are we wired to need relationships? Why is there love? Why?
