has_many :through - Circle of death

@xternal @jackdempsey my take on tech debt:

Any advice on how to break the cycle? Reflecting on my own development experience, I think I need to be better at detecting when I need to stop and take a break, and when I need to motor on. Its not just fatigue - I do great work when fatigued, and also do crap work. Its a complex equation of complexity of the problem domain, fatigue, how long its been since I last worked on this bit of code or problem domain, and just the random fluctuation between "smart days" and "not so smart days". There's also this tension between wanting to have extended focus over time on a complex problem domain so I can get the whole thing into my head, and taking breaks often enough so that I don't make mistakes or lose creativity.
