When building a business, it requires some level sacrifice and discomfort, after there have been significant growth l, money can be spent for expanding the business. At this point, it is not referred to as spending but as investing, because the changes and expansion will bring in more profits.
If you are talking about making sacrifices while trying to grow a business, it is understandable but putting yourself in discomfort just to achieve some level of growth in your business is an idea i wouldn't want to buy. I mean why put yourself in a state of discomfort, you can cut your expenses in the course of enhancing your business. When you invest more in your business it will yield more profits for sure but it also depends on the kind of business you are dealing with because there are businesses you will want to expand and end up losing because as you are expanding your business, invariably the cost of the things you market may increase which can cause low patronage because you can lose some of your customers who buys things from you cheaper initially but since you expanded your business and increased the cost of your products, they may find it difficult to deal with, instead they will prefer where they can buy them cheaper.
