It's kind of like that last mile of running a marathon. You've already got 25.2 under your belt - you know at this point beyond a shadow of a doubt that you're going to be finishing the race. Completion isn't in question anymore. Although your legs are still moving, your brain has moved on to thinking about post-race.
Very nicely put.
I live within earshot of a busy road and it sounds like a machine ('the grinder' I call it). As I get into my car in the morning, I imagine that I am throwing another day of life into it.
Yesterday, I had a really nice morning, sent the kids off to school and my wife off to her new job. I usually go to work before them, but work is slow and the home life was flowing nicely. After they left, it was nice that I had somewhere to be, but wasn't in any hurry to get there. The traffic had died down by the time I hit the road and no longer sounded like the grinder. When I got to work, I compressed the whole day into a reduced 5 hours (plus one hour for lunch), which was much more tolerable.
I get every other Friday off, so I'm at home now, but need to head to my kid's school (on my bike!) to help out with Eureka Science. The rest of the day will fly by, but I think that I savor days like today more because they are infrequent.
I'm pretty happy with the status quo. It will never be perfect. I guess I would quit my job if I found something else that made money (doing stuff for free all the time is a conflict for me) and/or felt fulfilling (applying skills to solve real problems).
I think early retirement will be nice, but now that the kids are older and don't need us as much, I'm not sure if I'll feel fulfilled. Worse yet, my wife might start to give me the same line I used to give her - 'what do you do all day??'.
The perfect situation is that my employer lays me off, which has been happening more frequently around the office. I'd get a severance and have a bit of an excuse for a while as to why I'm at home. I feel terrible, because my neighbor got laid off 6 weeks ago and he's desperate to get back to work, so I certainly don't talk like this with anyone other than you strangers :)
