This applies to so many areas of our lives. I try to keep this in mind when considering selling a loser stock for one with much more upside potential. I used to believe "you never lose money in the markets unless you sell a stock and unrealized losses become realized losses". Then after year of sitting on unrealized losses and going nowhere, I decided that my belief was full of crap and I wanted to own stocks that are actually going somewhere.

Then, consider retailers...some developers will purposely build outlet malls in hard to get to places (Like Barstow, CA) so by the time you spend the day there, you'll be more inclined to buy something because"you came all this way" and want something to show for it. Those tricky bastards!
