Don't turn uncertainty into fear. This is a mistake addicts make. Remember that you can't know everything. You can't predict anything (outcomes especially). For example, you can't know if a law will change, how an investment will perform, whether you will get that job, or whether you will get sick. No amount of money can resolve uncertainty so don't sit at a bar crying about it. Uncertainty is a natural way of life for all of us.
Have a busload of faith that your Higher Power will give you no more than you can handle. Your Higher Power can be whatever keeps you serene without bad consequences (group support, faith, the act of helping others, spiritual principles, the loving universe, a religious God, or a non-religious Higher Power, creativity, a Good Purpose, the 12 steps, etc.).
