This article is one of my favorites. Even though it is about focusing (or specializing), what he ends up describing is "multiple streams of income." In fact, I think it's almost a requirement that in order to have true MSI, you must focus -- that's the only way to earn more without increasing your time committment.

In my opinion, the most time-consuming aspect of establishing an income is the learning phase. That's why it's wise to take increased advantage of what you already have worked so hard to know.

P.S. -- What do you do if your specialty suddenly falls out of favor? Don't abandon all your hard-earned knowledge, instead re-position yourself.
