Profit will be one of the priorities or as a goal for business people, so many business people only focus on increasing higher sales targets, so they forget about investments that are the balance of their business, especially when sales turnover decreases so that profits are getting smaller. So investment is also very important, especially when the business is running smoothly and there are big profits, so business people should save some of their profits for investment. Is there any reason for you why business people should also invest?
