There is, and has been, a huge movement of people into entrepreneurship. Employees sometimes think that they know more than their employers do and, sometimes, they do. They also tire of reporting to someone else and having little control over their lives. Sometimes, good employees lose their jobs and have trouble finding a comparable position in a down job market.
There are many reasons to consider starting your own business, however, entrepreneurship isn't for everyone.
To be successful as an entrepreneur, you need to have a number of talents or enough money to hire people who can do the things that you either don't know how to do or don't want to learn how to do.
