Recently, I've been attempting to cut back on my work. I'm a bit of a workaholic and I can easily fill my entire life with my day job. I've made a subtle but effective tweak in the past few weeks: after the workday ends, I turn off work email notifications on my phone. That one little tweak, which is trivial to do because of the power of my device, has made me more present at home and I've worked less in off hours. I can still easily check my work email from my phone, but I'm not getting the notifications. I don't give myself the space to be distracted.
This happened to be the right adjustment for me in one arena, and I have others to evaluate, recognize and change. However, the point of my anecdote is that I adjusted my own behavior and forced the power of the distracting tool that's constantly in front of me to work to my advantage. I'm also reading more these days.
I understand David's refocus on specific topics. For me, that would be a loss - I like reading books and browsing them in vast collections (i.e. public libraries). But the downside is not being terribly expert in any particular area. Were I still 30-ish, that'd be a real liability. So, it's a tradeoff.
