I hadn't heard of that before. Amazon.com says it's out of print. Here's a link:
Don't Ever Retire-But Do It Early and Often
Here are a couple of links to a list of possibly relevant book reviews from the Retire Early Home Page:
(Re: _Rich Dad Poor Dad_ reviewed in the first link: I bought and liked this book at first, but if you'll follow the link under that review there are some important things to consider before taking this book's advice.)
Burnout is a frustrating thing. I've toyed with the idea of going part time or 'semi-retiring', but in my case it's probably very unwise.
I burned out at 30 (I'm 33 now), quit my steady job and went to an IT startup company that promptly went bust. I took 3 months off, but I didn't cut enough spending first and wound up running my debt much higher, and I probably set myself back 2 or 3 years finanically. On the other hand I became much more humble (which can be good), and during the time off I learned a lot about personal finance and business and job hunting.
Full time jobs and careers aren't fun, but they're the most common way to earn money and save for early retirement.
I was just reading a web site a couple of days ago about a family that lives in Washington or Oregon; the guy runs a one-man carpet cleaning business, and the family lives on his income, but he takes lots of time off for vacations. I thought I found the link on the REHP site, but I can't find it now. I know I bookmarked it somewhere; I'll post it if I find it before someone else posts it. He write a lot of essays, many of them about his relatively low income lifestyle and his fun and travels.
Guys like that and a couple of "ski bums" I've met have very interesting low-income lives. The ski bums usually work as ski patrol in Colorado during the winter and take odd jobs like raft tour guide or archaeological dig helper in the summer. (When an oil company hits archaeological artificats, by law they have to call in a team to excavate the site; usually a university does it and hires locals to help.)
However, I think I'm a bit too spoiled to having spending money to make it part time. And as far as I can recall, everyone who's retired or near retirement who's posted here got there by either saving a lot or earning a lot in a short time and the drastically cutting spending. I haven't heard of a long-term semi-retired person here yet. So I'm guessing my best bet is to follow in their footsteps.
Also, if you take some time off, be aware that it may look bad when applying for a job. I had the worst time finding a job after taking 3 months off. Of course the IT industry had just crashed, but I had good solid experience, a 2-year degree and technical certifications and wasn't even getting called in for interviews. I really think the 3-month gap disturbed employers.
This post got much longer than I planned, but I also wanted to talk about burnout some more. If you're burning out, plan ahead. Either deal with it and adjust or make sure you can handle what happens when you leave your job. I put the cart before the horse and left without getting rid of my expensive truck and paying down my credit card debt. I also didn't have a very secure job lined up. It can be much cheaper to adjust your attitude before quitting your job. Read up some on burnout; some of the causes surprised me (uncertainty/instability, for example), and there are ways to deal with it before it consumes you. It probably wasn't wise to quit my job when I did, but my attitude was getting worse and I knew I was going to get in trouble sooner or later because of it. Get control of it before it gets that far.
Okay, I'm off my soapbox now.
