About #5, I disagree. In the past, I would wait to buy a product till I "think" I have enough knowledge about the product. However, the downside is that if you delay your purchase to decide if you truly want the product, you will end up "thinking" about the product each passing day until you have bought it. You wouldn't have to do this "thinking", if you purchased it right away or with little deliberation. There are two ways to satisfy an urge to experience a "want". One is to get it right away or the ignore (not suppress) it. Ignoring is quite difficult, right-away execution is much easier ;-)
