Today I went to the mall as I was trying to research about the price and availability of a certain item. Since I did all that traveling it kind of seemed wasteful to not buy something and so I was thinking if there was anything that I justifiably needed to buy. I was then thinking that the dress shoes I was wearing were a little bit worn out in the front and so maybe buying a new one would be too bad of an idea.
But the other side of me was saying it may be a little worn out, but for the most part it was still an acceptable quality where I can use it daily. Therefore, it would seem like a premature purchase that will simply drain my money. I just have a habit of using things until they are unusable whenever possible. Even if they are worn out I would try to find ways within reason to keep it going.
Unless you are talking about something that poses say a health issue for not replacing it. But in those cases I would consider that as unusable too.
