I have just started reading about LOA and I have a couple questions... First, lets say I want something but it is not very specific, like for example, I want a job that pays well and I will enjoy, however no specifics about what kind of job or anything so it's difficult to visualize. Will the LOA work for something like that? Second, what if it is something that way be physically impossible? For example, what if I was wanting changes in my physical appearance which are just not possible? Would it somehow work in a different way? Or would it just have no effect?
