4.4.0 Entrepreneurship 4.4.1 Introduction What is an entrepreneur? This is an individual who creates a new business, bearing most of the risks and enjoying most of the rewards. He/she is commonly seen as an innovator, a source of new ideas, goods, services and business or procedures. What is the entrepreneurship? This is the capacity and willingness to develop, organize and manage a business venture along with any of its risks in order to make a profit. The most obvious parable of entrepreneurship is the starting of new businesses.
4.4.2 Risks and Rewards of entrepreneurship a) The Risks of entrepreneurship Loss of assets by theft, fire and natural calamities Sometimes it might not be easy for an entrepreneur to secure the properties made against the thieves, fire and natural calamities, hence they might be lost. Sacrificing personal capital Most of times entrepreneurs have to use their own savings to get their business off the ground until they have developed it enough to be ready for external funding from angel investors, government grants, loans etc.
Relying on cash flow It can be a real challenge to secure sufficient cash flow in your business on an ongoing basis. This is particularly true if one of your bigger clients pays late or you loose a client, then costs can quickly exceeds your revenues and you will need to tap into savings to pay the bills. Interest in your product or service Even with a lot of research and tests, you only have an estimate of people s interest in your product/service, and that interest is somewhat unpredictable. Trusting key employees If you are starting your business, you won t have the resources to hire a full team, which means you will have a small group of people putting a lot of effort into the product to get it going. Meaning that you will have to put a lot of trust in this small group of people to get the job done.
Betting on a crucial deadline Finances are often tight in a start-up and investors want to see the progress, which means that several milestones can be tied to a certain deadline. Entrepreneurs usually worry about hitting the specific deadline. Committing personal time You will spend countless hours working on your business to make it successful, which will make you miss out on personal time and sacrificing health. Emotional risk Starting a business means that you will go through an emotional rollercoaster, there might be jealousy of a competitors who got into press, self-doubt, limited time to see your friends and families, feeling of rejection by investors, problems with your co-founders or employees.

Excitement Building your own business can be a very exciting and highly enjoyable process as you get to apply your skills and abilities to solve problems, meeting interesting people and working with people who are not only customers/suppliers, but also your friends. Flexibility Since you own the company, you can decide how to organize your schedule and when to take time off, but the truth is that the entrepreneurs often have to work very long hours, especially in the beginning.
Freedom You have the freedom to choose if you want to work from home or while you are travelling and you can choose when you want to work. Impact You get to see the impact you make first hand as you work closely with your customers and the problems you solve make a real difference in people s lives. Rational salary You salary is directly related to how much work you put in and how many new contracts you close. New skills Even if you have expertise in certain areas, in the beginning you have to do a bit of everything and this way you will learn about accounting, design, marketing, public speaking, how to delegate, creativity, etc.
