There is a fine line between what we want and what we need. Sadly, often the temptation to get what we want is far greater then what we need, especially if we don't have any financial, emotional or physical setbacks.
Getting things that we need gives us a satisfaction, knowing that everytime we need it, the thing is already there.
But getting things that we want.. indulging ourselves, listening to the little voice in our head shouting out "Get that damn thing already, you know you want it!" over and over again, and actually doing it, that brings satisfaction to a whole new level.
Almost like having a piece of heaven, a very small piece of it, but still, a piece of heaven indeed.
