I have never had any problems figuring out how to fill my time. In fact, I still don't think I have quite enough time. I know this can be a serious issue though. The best book, I have read is
Zelinsky's The joy of not working. http://www.amazon.com/Joy-Not-Working-U ... 1580085520
In the ERE approach, learning skills on how to do things yourself to save money is one way to fill the time. Actually doing the things takes much less time. It is often faster than going out and buying them in the first place.
Saw this one. I just got a San Jose library card, since I've been working at the Library this week. Just reserved the book no less right now!
RDPD is completely checked out. One copy is MIA according to the site.
