This all seems very tempting, but on the other hand, there are a number of disadvantages. You have to make a lot of big decisions, for example whether to expand, or whether to employ new staff. This is often very stressful. Although you are the boss and in theory can decide what time you finish work, you might find that instead of finishing early, you have to work all night because of an important deadline. Finally, there is an element of risk. If the company fails, you could lose not only your job, but also your home and your life savings.
