I don't know that my age has increased my wisdom on this matter, particularly. Those of you who have been reading this blog for a while are familiar with the loop where I grumble about having less freetime/popularity/published works than I'd like, and then acknowledge that my life, as it is, does not actually suck. In fact, it's pretty good.
There are days when I can be at BHFT and feel really happy (such as the day before I got slammed with this latest cold). I do know that happiness is not tied to material wealth or income (although health is certainly a key factor; I rarely feel really happy went I'm sick, exhausted or otherwise afflicted). So I don't know if I need to quit my job and pursue a creative career, as is the trope, but I'd like to have more days of bliss in my life. As I become more and more conscious of the seconds slipping by, I foresee less and less satisfaction in merely doing okay.
I don't know what the next year will bring. I could be on the verge of some big shifts (but I am quite satisfied with the car I currently have). I don't know. We'll just see.
