Re: a book
Gillette Edmunds has a book "how to retire early and live well on less than a million dollars" or similar title...if you cant find it let me know and i'll go look for it. Short, quick read, covers most of the asset classes and provides some decent opinions on investing.
Unlike 'the four pillars' and 'the millionaire next door', you can actually read this in an evening sitting and not feel like your brain has been replaced with a chunk of concrete.
Be fearful when others are greedy, and greedy when others are fearful. Just another form of "buy low, sell high" for those who have trouble with things. This rule is not universal. Do not buy a 1973 Pinto because everyone else is afraid of it.
