Wanting the Best

I have always been the type of person that when I purchase something, I try to research it so that I don't waste my time and money. Some people say I have to have the best, but I don't necessarily think that is so, I just hate to waste time and effort. For example, when I was looking into the best weight loss product I could buy. I wanted something that worked. I didn't want to spend days or months trying something that wasn't going to give me results. I don't see anything wrong with that, do you?
