Great for the upside of growth - how do you change it for when you start to age and skills erode a little bit. That would be deeply frustrating. Need to change the model at that point! What to though?
Your skills don't age like your physical body does.
That is true, but the rapid change in the tech industry makes "skills" mean something different than it would in, say, woodworking.

In our industry, to 'stay at the same place,' you continually have to learn new technologies, new concepts, etc.
