I had tried few different ways to invest and found the "coffeehouse investor" book to be pretty good guide on how to invest by spending really little time.

Book is really short. But you don't need to buy the book. The website lists the index funds, the returns over last 20 years and portfolio %. I am mostly invested in Vangaurd index funds and it has worked out well for me.
