I read that book a couple years ago. It has completely changed my thinking. I'm starting to take some steps in that direction.
You have good goals, however you probably won't be able to achieve them in only 2 years.
Start with paying off your credit card debt. Credit card debt is never good. Stop using your credit cards as well...pay for everything with cash. For now, the way to success is to minimize unnecessary expenses so that you can put as much money as possible toward your other goals. Books that provide fantastic guidance toward paying off debt are those by Dave Ramsey (he is very debt averse and would probably disagree with much of the Rich Dad philosophy, but has the best debt elimination plan I've seen). Eliminating credit card debt before med school is one of the wisest things you can do.
Other books in the Rich Dad series are good, despite a lot of repitition. I'd read some of them in the library or in Barnes and Noble, don't buy them.
You'll need some support and guidance to achieve passive income goals. Start by going to the rich dad site and look for a cash flow club in your area. If you can't find an active club, try to find out if there is a real estate investors association in your area.
It took me several tries to find an active cash flow club. I met the leaders, and they hooked me up with real estate investors club. There I met active investors (whose sole income is from real estate) and brokers who all invest in real estate themselves (most of them do flips in addition to owning rental property). The result...in less than 6 weeks I have been able to find my first property, a duplex which I can purchase with government sponsored FHA loan, 3% out of pocket (as long as I live in one unit). We will close in about 2 more weeks. Once I met the right people, things started happening so fast it's a little scary. I'm also educating myself on the stock market, and am starting to allocate old 401K funds to self directed IRA.
It's hard to imagine you would be ready to buy a house before you start medical school, and I dont' think I'd recommend it. I think your goal should be to pay off your debt, and minimize your med school debt.
You do need to realize that med school and residency will be very time consuming, thus making it difficult to find time to pursue other income streams. It does take a lot of work to do other things. Kiyosaki worked hard to build a business, which failed and was rebuilt. He then sold that and started an education seminar business and bought a bunch of rental property. When he met his passive income goals, he retired and then came up with the Rich Dad idea. He started with the Cash Flow game, and then wrote the book and started the rich dad company. The company decided to publish the book as a way of selling the game. (This story can be pieced together from all the other books) So he wasn't financially free until age 47. It certanly can be done, but it takes time and a lot of work. Time is something you won't have in med school and residency. Maybe you should think about revisting your goals...you might want to postpone med school.
If you've seen my other posts, you know that I started surgery residency and then became unhappy with it. That unhappiness is what drove me to do other reading, which included Rich Dad and others. I quit residency, and am working nights covering surgical floors. My plan is to start anesthesia residency in a couple of years, but meantime I'm giving myself some time to see if I can get some passive income going. My level of success in that area will determine when (or if) I apply for anesthesia residency.
