I was just saying, why is it a bad thing to know what you want?
Not until what you want changes and there is a wife and a kid who depend on you for support. When your wants change because you haven't had enough time to experience life and find out what you really want then yeah, knowing what you "want" can be a bad thing.
People have 7 - 10 jobs in their life, the divorce rate is at 50% and Obama's approval rating is at 20%. People change what they want in life, it happens. You may end up being that statistical anomaly but it's unlikely. What you want now may change tomorrow, next week, next month, next year, next decade, and then may change many times during that time as well.
Who knows what your reasoning is, maybe you are a child of a divorced household, maybe you were a foster child who was bounced around, maybe for some reason you crave stability and normalcy in your life that you think getting married and having kids will give you. Who is to say what your reasoning it. There is no way you could give us enough information to figure it out. Even if you could it would have a self serving bias to it so whatever you tell us would be from your point of view to make it sound like your reasoning is sound.
In the end, nobody truly gives a shit what you want. Go out and do whatever you want and learn for yourself if you really want something.
