So my own anectdotal experience in this has shown the author's suggestions to be true. There's only one major catch that you don't start realizing unless it impacts you - your physical ability to actually absorb and retain continued constant learning. We have to work longer and harder (into advanced age) these days to survive. While many people can learn and adapt and absorb for a long time, I don't think it's true that everyone is that way. Some people, as they age, have more trouble being able to constantly learn and instead end up "stuck" at a certain level of knowledge/skill/ability. In the world of tech where you can get flattened competitively speaking if you fall too far behind, it's incredibly difficult and can become infeasible. Especially difficult if you end up going down the path of memory related diseases. For example, in my family we have dementia running in a few generations. The onset of dementia often shows itself in small ways far earlier than advanced age, for example, the inability to retain short term memory can kick in much earlier. This is one thing that drove my feeling that I had to be as successful as possible and earn as much as I could when I was younger- not to be rich, but in case I literally was unable to keep the pace in the future. But on the bright side, I have aspired to keep my mind open and learning as much as time permits, as the author discussed. So far, my colleagues have always told me they thought I was always a font of knowledge and I always tell them that it's only because I keep trying new things. Not because I actually "know" everything I talk about, just because I try to dabble and learn constantly. I will say though, learning too much breadth, while really fun and a totally valuable way of learning (you start to see cross disciplinary patterns and connections between all kinds of things) - can lead you the "Jack of all trades master of none" conundrum.
