First, the love for a member of the opposite sex is a concept that is so distorted and trashed that it makes me sick. This love I am refering to is about devotion, honesty, and selflessness. Too often it is about money and sex. When it comes to marriage, people just don't take it as seriously as they used to, and as it should be. The fact that adultery is so commonplace makes me entirely disheartened.
People get divorces all the time, and some people get remarried like ten times.
Second, the love for one another that exists as friendships is also worth living for. Knowing that you can mean something to someone else and that you can make a difference in someone's life are awesome feelings. Maybe this also has to do with leaving the world a little better than you left it. That seems to be a good meaning of life also. Knowing that you accomplished something or that people can benefit from your hard work, experience, and love.
