“Yea… Life goes on… Long after the thrill of living is gone…”
I think everyone feels this but I also think it may be a matter of perspective as well.
Spend some time where people could only wish to have your problem. Volunteer, mission work, Peace Corp may just be the ticket for getting some prespective and making you feel better. Once that is accomplished you may have a zest for something again.
I am turning the big 40 in a couple of weeks and I am having that starring contest with the man in the mirror. Then I remember that I have achieved more than my parents (to thier credit), more than most of the kids I grew up with, more than any of my high school teacher expected and then I feel somewhat content. Not exhubriant but content.
But I do feel that zest ebbing away slowly as well.
