Yes, yes, there are harsher worse ways to live.
I too have a cush government job, so I do not have much to complain about compared to corporate slaves. More free time than most. It's just sitting at the computer all day, being surrounded by people that are not as interested in ideas and learning and problem-solving. There is little that gives one energy or hope or meaning or creativity, even with my best efforts to improve the situation and change my attitude.
I am left with a gnawing sensation that I should and could be doing something more with my talents. But the immediate alternatives--quitting, jumping jobs, going back to school, moving around, indulging in addictions and love and escapes--will not fill this need. As a well-seasoned traveler, I know there is much more to life than the usual work routine. The path to what I seek is long and arduous and will be full of stumbles and self-doubt and critics. I think more than anything, I seek time freedom, doing something of value to others, contributing something positive to the world, and leaving a small footprint while exploring as much as I can.
I read a wonderful little book not too long ago, The Yellow Arrow by Victor Pelevin. One phrase sticks with me: "'There is only one path to happiness,' his companion said authoritatively, scraping his spoon in his bowl. 'To find meaning and beauty in all of this and submit to the great plan. Real life only begins after that.'"
I include that quote because it is seems to me the perfect embodiment of the idea of appreciating the things you have every day without obsessing too much over what your life lacks or that happiness/fulfillment/satisfaction is some fuzzy destination in the future. In the weekly routine, these simple ideas often are forgotten.
Sorry I rambled, but these are just some thoughts on my current situation and I am sure something that affects many other people.
