Honesty and responsibility are the hardest to learn. Be honest with yourself and take responsibility for your mistakes and you will be well on your way to making good decisions under stress. Excuses cloud your judgment. A good way to start teaching yourself is to make a list or schedule for yourself each day. Set time frames for each item. As you complete them mark them off. At the end of the day look at what all you accomplished. Where you on time? Did you get everything done on the list? If you missed any times or items figure out why. By doing this exercise you can learn to be honest with yourself and responsible and it helps you identify problems as well as solutions. You begin to learn what you are realistically capable of in a give time frame and how to problem solve as well as prioritize. As you get better add more items or give yourself less time to do them. It will produce a little stress but it will begin to at least train your mind. It may not be levels experienced in SHTF but if you are lacking in this area it is at least a place to start.
