Indecision

I hate making big decisions. I wish there was a person who would, for free, take a look at my life and finances and tell me the smart choices when it comes to things like, "Can I afford a bigger house, a newer car, a car for my kids to drive (cuz that's coming, you know), and then our usual fun, clothes, holidays, etc...???" Why can't I figure out the answer to that question? Am I that dumb? I can't decide anything due to lack of sufficient information!!!
