Another way running a business changes the way I think is the value of time and the ROI on temporary things. Most non-business people would hesitate, for example, to buy proper furnishings for their house or upgrade their tools/workspace if they only plan to stay somewhere temporarily for a few months, but I would do it because of how much more enjoyable and productive those few months will be if I had proper facilities, which may have a far greater ROI than simply saving money for a few months.
