I dunno what to do???

Ok I'm having a little trouble deciding on major...I really dont see how people do it because its such a life changing choice. I know you can change it but that is time wasted so how do you know what to choose. I feel very indecisive when it comes to making big decisions like that. How do you pick how your going to spend the majority of you life. I dont want to do just one thing for the rest of my life. My life is so multifaceted why should I have to narrow it down to one thing. I can't! People also always say that what ever you have passion doing that you shouldn't worry about the money...it will come. That is not always true. These days you have to look at the pay with a job. I hate it but it does matter. You have to make sure that your career will support your lifestyle. So its not all about doing what you love because what you love wont always pay the bills. I hate money but its part of everyone's life whether they like it or not. Life seems to grow more and more complicated and all I want is to be happy. Is that so much to ask? To live happily ever after...
