Thanks to TTL for putting up a couple of interesting links. For instance, Steve Pavlina writes about why you should never ever have a job. Basically he says that being employed makes you a slave or a pet, while being self-imployed or a business owner makes you free. Perhaps I am an odd person to argue against that, for am doing very well on my own and I love it. But I am lucky. I know many business owners who work longer hours and earn less than the people they employ. And they have more ulcers as well.
Especially if you work for a small company where the boss is somebody you can talk to, there is something to be said for being employed. Maybe your real interest is rock collecting, and who can earn money on that? Maybe you enjoy your job and your colleagues, and go do your stuff on your own time. I certainly don't regret a minute of the time I spent as an employee, I had fun and I learned a lot.
Basically freedom has very little to do with your physical circumstances. Freedom is in the mind. A millionaire can be a free man or be trapped by his mind, and the same is true for a bum.
There is more I agree with in Steve's articles about a new business, and 10 lessons for entrepreneurs.
Update: He is right, though, about security: I had three jobs which I loved, and all three ended when the employer could no longer afford to keep me.
And now I've been self-employed for ten years (in March), and there has not been one lean month. (Obviously this is a bit exceptional, I'm just presenting the opposite side to the coin here.)
