I don't believe in retirement. To me, retiring means two different things. One of them means to be able to have time to do other things that you enjoy (the other is something we'll talk about in some future lesson). That kind of implies that up until then, you never had the ability to do the things that you actually wanted.
Which brings up a much more important question than how to retire early. Even if you had all the time and money in the world, do you know what you want to have and to experience in life?
