Relying solely on a 9-5 job, even when you have a good salary, might still not cover your entire financial needs. For instance, you might not be able to buy your dream car, or dream house, or go on a vacation. Paying your bills is not the only thing people do with money, they use money not only to buy properties but also to enjoy life through various activities that require money. Therefore, you need to explore additional avenues like working on a side hustle, investing, or starting a business.
