I've been reading a lot of books on finance and financial literary recently (Robert Kiyosaki's books, stock market investing stuff, etc). One of the main themes that has been stressed is the importance of passive income; making money work for you instead of you working for money. As one gets more passive income streams through investments, a dentist can possibly work less and/or pursue other interests. I recently found this web site that focuses on passive income for medical doctors, and I found this particular article to be a very good read on the benefits of owning real estate for rental income. If you guys have other tips/ideas for dentists to make passive income and/or your own passive investments, please feel free to contribute to the thread.
