Why Does It Matter What You Believe If You Don't Stand For Anything?

I had an interesting thought today. Some people are skeptical to believe certain things while others are less skeptical. Some people require a certain delivery of the message to swallow it. Everybody has different believes and values.

My point is, why do you care what you believe in? The only reason somebody would care what they believe in is if they cared about their foundation and their goals. If you can't have any objective and nothing to build upon, why do your believes matter at all?

I'm not saying this to anybody in particular, but more of a philosophical conclusion I have reached. There is no point in caring what you believe in unless you care about who you want to become. And if you care about who you want to become you must have a goal or objective. You must have something at the end of the road that each belief will lead you to.
