There is something that I don't think a lot of people get. I see it every day at work and I see it in the way people behave when it comes to their finances. There is a cost of being.
What do I mean by that? Let me give you an example. We have a core piece of technology. On top of that core piece of technology, we have added many small features. At the time of inception, and without giving it full thought, these features may have made sense. They were easy to implement and brought in incremental revenue. This is revenue that is rather insignificant but nevertheless is revenue. Since this is web based, the "cost" of running these features and services isn't very much, it just means keeping a web server up and running.
However, there comes a time in any feature that something doesn't work. It may be the feature itself, or the feature may have some side effect that was unintended. When that something doesn't work, the impetus is always to fix it because you don't want to have broken parts of your product. So there is a cost that must be born to fix this almost pointless feature. There is even additional cost when you factor in that you will now spend time worrying about if this feature will break again. This feature can even go so far as to holding other features up because you can't launch new product while the current product is broken.
The same goes with people in their everyday lives. Just look around at the things you own that you probably never use. I've complained before how, during my move, I found boxes of things I moved up to Seattle that I never even opened, and was now shipping right back to L.A. This has a cost both in terms of the move and in terms of me storing it for years. People have extra cars they don't drive or gadgets that just sit on the shelf, only ever used once. All these things have some cost associated with just "being". If we just got rid of all these small, incremental cost, the total sum of the savings would probably be quite significant.
What do you have like this? What insignificant things do you just keep around that, if you think about it, really have a cost?
