The quality of your choices will depend greatly on your mental state at the decision-making moment. Your choices will be different if you are at your wisest and best.
When you are at your wisest, you think more clearly. You weigh your options more skillfully. You give greater thought to the possible outcomes of a specific course of action. You realize when something is not a good idea. Since your quality of thinking is at its highest, your decision will be the best choice that you can make at that moment.
When you are at your best, your talents and skills represent your best efforts. Remember your best moments and utilize this to create your wisest and best ways of thinking and acting.
