Just a random thought - I thought I'd post it here. How do you define the richness of your life? I don't mean your life right now, rather when you are eighty years old and look back on your life, what criteria would you use?
Many people try to live vicariously through their kids and grandkids. They link their success to the success of their kids, usually the conventional indicators - job, house, car blah blah blah. Others simply look at their bank balance. [I'm not dissing the importance of money, in fact I wouldn't mind being a rich lazy dilettante :-)] There are so many other things to consider - time spent being happy, a successful career, sex, circle of close friends, vacations etc etc.
It will probably be a combination of the things that I listed above and some more. But what I would value the most is the sum total of unique, different experiences. The more unusual the experience, the better it is. For example, last week I trekked alone in temperatures of -7 F (-21 C!) to get to a frozen waterfall. It was not particularly eventful, but I will cherish this day trip far more than a conventional vacation. In other words, what I don't want is a monotonous life.
