One of the problems that come from tying happiness to satisfying exterior wants is that what we want is not always realistic. When we desire or must have this product or that gadget and think we must have it to be happy but the money or the supply is not there we will be disappointed, and worse, distracted from finding the things that can really make us happy long term.
We live in a world that literally sells us the idea that we can be happy if we have things and that no matter how much we have we could always use the newest model of it to be that much happier. We live surrounded by the din of advertising, salesmen and peer groups who show us that this is the right way to live.
We have to be on guard every minute to make sure the voice in our head telling us what we want is our own voice. How will this gadget satisfy a need in our life? How does this product make our lives better? Is this a real need we have? Is it an area of our lives that needs improving? Being able to sort out our real desires from those placed there by advertisement is one of the basic steps we need to take to find the direction to guide our lives in.
