Something I don’t do enough of and that seems like maybe the author might also benefit from emphasizing is getting way out of my comfort zone with my projects. I tend to huddle in this distributed systems / commodity ML / tight C++ cluster: stuff good for scaling consumer websites but not really dead center for much else. I need to do some hardware (or at least some embedded systems), some phone app stuff, some web stuff, and a zillion other things. The author seems to be fairly tightly clustered around PHP/web/REST stuff. All that stuff is useful and important but focusing too much on any area can get stale. At least for me.
