Entrepreneurship is considered risky because there is no guarantee of success. Starting a new business involves uncertainty and challenges, such as market competition, changing consumer preferences, and economic fluctuations. Entrepreneurs are often required to invest their own time and money, and there is a chance that they may not see a return on their investment. Additionally, entrepreneurship requires taking calculated risks and making difficult decisions, which can lead to potential losses and failure. Overall, the unpredictable nature of entrepreneurship is what makes it risky.
