I like this simplification. I think there are loads of other options though. You could invest in a new business. There are many business that can be very profitable. I don't this is the best time to get into it, but mining could be a good option too. I think real estate can be one of the best investments if you go about it properly. If you get into rental properties, you can pay off a mortgage, so you will have a property in the end, plus you'll get a little bit each month for yourself.
