Should I use guided visualizations to attract positive life changes (manifestation)?

I've heard that guided visualization can be used to manifest goals and attract positive life changes. I want to use it to overcome my financial anxiety. Is visualization truly a tool for manifestation, or should I just use it for simple relaxation to cope with the present?
