<font color="yellow">What prompted these people, after their astronaut careers were over, to lose touch with reality?</font><br /><br />I've thought about this one before. I've had to deal with this over and over in my own life. I've finally realized that it is PERFECTLY NORMAL HUMAN BEHAVIOUR, in response to living a goal-based lifestyle.<br /><br />Goals are useful, but costly. Goals motivate us to achieve great things. However, the pursuit of a goal has some undesirable side effects:<br /><br />As we pursue a goal, we tend to belittle ourselves for not having achieved the goal yet. We tend to think in terms of being "behind schedule". To compensate, we begin to live an unbalanced life, focusing too intensly on the stated goal. We tend to "beat ourselves up" over an unreached goal. Getting there is hard work, and is seldom very much fun.<br /><br />...until one day... We reach our goal! Success! Jubilation! Fulfilment! Glory! ...for a brief, fleeting moment... and then...<br /><br />The "Post-Delta Blues" sets in. This little depression often naturally follows the achievement of a goal. The bigger the goal, the more the creative investment, the deeper the depression. It comes from not knowing what to do next! It is a kind of emptiness, a loss of usefulness. The same thing kills a lot of recently retired people.<br /><br />Apollo is my favorite example: JFK's goal was to "land a man on the moon, and return him safely to the Earth". We blew up a lot of rockets and killed a few astronauts along the way, while working like crazed madmen. It was very productive, but not very much fun. Then we did it, and had a few parades. Then what? WHAT COULD YOU DO THAT COULD POSSIBLY BE BETTER THAN LANDING ON THE MOON? Nothing! That's where the depression comes from.<br /><br />Now for the great lesson in life: Don't live your life this way! There is an alternative: the process-based lifestyle.<br /><br />Instead of setting goals, set a direction, and follow
