Baptism goals provide an answer to both your doubting thoughts and worried questions. (C) [substeps] For instance, a goal to lose twenty pounds is a good goal. A goal that is vague like " i want to get fit " is not measurable. (D) [substeps] For example, if you are looking to reduce your overall physical limits, you might set realistic weight goals.
