Sometimes I wonder who this kind of advice is written for. What kind of attitude or perspective does someone need to benefit from this advice? How much of it is written for the author to say it versus someone to find it useful? I think back to the people in my major who had obviously never had a higschool job, nor worked on a project that required them to engage in problem solving (outside the highly structured and guided problems in school assignments). Most of them figured out what work is, bombed out, or gave up. A few were still around in senior year, having found new ways to skate by. People are under-served by the systems we shoot kids through. And my criticism is not in the typical "we don't train for X" way. Not only are there infinite X's, but the system creates expectations and boundaries that adding more Xs just entrenches. A person can be perfectly competent at some set of tasks, able to be trained on others but still see everyone (including themselves) as cogs in a finished system solved by the smarter people. What I'm getting at is the lack of insight that lead to the time a friend of a friend saw my roommate watching a youtube video on the TV of something being built and asked "Why are you watching this? Just buy one at the store." At the time, that statement was as bewildering to us as it was bewildering to them that there could be value and entertainment in watching and understanding the process.
