randomly browse bookstores or websites looking for something to read.
Since I've read everything I want to read off of all the science fiction lists I can find on the web, I usually just sample stuff on my kindle until I hit something I like.
Grab a bunch of books that look interesting from the library. Start to read. Discard crappy ones until I hit one I like.
Wife works at library.
I got 99 problems but looking for my next reading material all thanks to my wife who works at the library ain't one.
