There are many benefits of starting one's own business. For instance, one can set his own hours and work from home. With the right business, one can be mobile, working just as easily while vacationing in Paris as while in an office. Also, one's own business can create a passive stream of income, which can leverage one's time more powerfully than the traditional concept of working for an employer 40+ hours at the office.
So, I'm thinking of starting a new business. Here are some ideas:
Translation service (Mandarin Chinese to/from English)
Researcher for hire
Make beef jerky at home and sell it -- all sorts of flavors, very tasty!
Write blog articles valuing businesses, companies, and stocks
Personal finance budget consultant
Which of these ideas would you be most excited about? Do you have any improvements on the above?
