Query: Practical advice, but not dry like a martini.

Kanbar spills all his secrets about how to be successful at inventing, where 'inventing' means more than just coming up with a gadget idea. He goes into great detail about marketing, naming, patent rules, etc, in a personable style. Sometimes, I got tired of hearing him blow his own horn, or plug his products, but I forgive him. That is what he does for a living, and he can't stop. The back has useful legal forms, and many refs to useful books and web sites. My favorite part was about how you must look around you and see problems as opportunities. Thanks, Scott!
