I'd like to believe the meaning of life is to find happiness with yourself, in whichever way you choose. Some seek education, some seek to copulate with everyone in sight,some just want companionship, others to make families and raise them.In other words: To live like YOU want.
I myself will have lived a happy life, so long as everyone around me was smiling more than not. If I can keep my family and friends laughing, through good and bad times, I'd go peacefully in the end. It's been said, I don't think there's just one, flawless and truthful answer.
Over-thinking and over-analyzing things are things we humans do all too often.I'd just rather not think about what purpose my life holds; and just live it.
