My wife and I had both planned on working until 66, which we are now, but my employer went through 2 rounds of layoffs and one caught me and my wife's company folded up at almost exactly the same time. So, we were both out a year earlier than planned which was unfortunate because we planned to put a lot of our 2 last years away. But, we were both so sick of corporate America that we just said screw it. My severance carried me through almost up until full SS retirement age, so not too short. We didn't get the mortgage paid off because of that last year we both missed which makes it a bit tighter than planned, so I'm thinking about something part time within the next few months to fill in.
The weird thing is that, while I was working, all I could think about was having enough time to pursue the hobbies I only had been dabbling in the last several years. Now that I have the time, I don't seem to want to do anything! Just sit on the couch, read my books, drink coffee and pet our kitties. I'm angry at myself for being this way but so far, that hasn't helped. Maybe working some, so that I feel a sense of urgency about time again, will help.
Edit: ...I did look forward to it mainly because I really hated all but two of the jobs I ever had.
