In the physical crafts there is another aspect of "enslaving ourselves to an ideal or goal" mostly revolving around safety. How many decades ago was I taught to never power up a lathe without immediately touching the chuck key in its holder (aka not in the chuck...) or never touch a table saw blade (while changing it or screwing around with adjusting it) without immediately prior touching the metal of its power cable (aka not plugged in) None of those are taught as in book learning but taught as in a discipline. And look, all these years later, still got all my eyes and fingers!
