2018 Update from 2013 post
I wrote "Regret so far by: Anonymous " in 2013 and a follow up in 2014 on trying to get back the college job I early retired from like an idiot. Who would give up tenure at 55? Being "off" (5/13 to 5/14) was an HORRIBLE PERIOD in my life.
I did it in part because my wife wanted us to move elsewhere. I was depressed beyond belief and having terrible thoughts (yes, that.). I am telling everyone NOT TO RETIRE especially early.
I now have another college position since Fall 2014. Although nontenured, I like it. I also a part-time engineering position elsewhere. I am busier than ever now at 60 and happy (11/2018). I work 10 hrs/day 7 days/week making up for that "long awaited, much overrated retired period".
I was lucky to get these jobs and AGE DISCRIMINATION is a REAL THING. I faced it in job search.
Don't give up something you may regret and be unable to replace if you regret.
