Long term, have a set of ideals for what you want out of life. Your list will be different than others and that is ok.

Short term, identify the costs of the decision. Include opportunity costs for making different decisions. Try to frame the decision, including keeping the status quo, as a cost you are paying for a benefit.

Also, try to have an idea on the overall cost of making the decision is. A lot of people get into analysis paralysis because they try to make the best decision when the time and effort in making the best decision is most costly than making a good decision.
