This has little to do with preparedness but much to do with how to be responsible. When I saw the news today that Sarah Palin was quitting her job as governor, I was shocked. Now I can understand if someone has a family member in the hospital with a terminal condition or there is some giant scandal that would prevent you from doing your job (cough *Spitzer* cough), but I was taught from a very young age by my grandfather that when you give your word, you keep it. Even if the job turns out to be different or harder than expected.
I may be getting old and crotchety but people seem to give their word then bail out as soon as they get bored or annoyed and it isn't right. People will charge up their credit cards, get tired of paying the bills, then file bankruptcy. People will take a marriage vow then run for the divorce court as soon as the first big blow up in their marriage happens.
This is why, in the survival realm, that knowing who you can count on NO MATTER WHAT is so important. There are only a few people I know who fall into this category. How do I find these people? By watching. Actions definitely speak louder than words. As soon as someone tells me how good, skillful, responsible, etc. they are, I begin to have doubts about them because if you are good, skillful, responsible, etc. then it shows in your everyday life, you don't have to tell people these things because they will see it in your actions and in your work.
The people who fall into this NO MATTER WHAT elite category keep their word, they pay their bills (if they lose their job, they will pick up three jobs just to be able to make their bills because they had made a deal and intend to keep it), they behave reasonably and aren't flaky, they don't cancel if they have given their word unless they are in the hospital, and you can count on these people for ANYTHING--money with no questions asked, they will drive 200 miles to pick you up if needed--basically they have your back and you would happily return the favor.
The bottom line is that being responsible is a full time, lifetime job. How you handle responsibility, how you keep your word, how you respond when times get tough show the world the quality of your being.
Done ranting now and hopping off of my soapbox.
