Hasn't been accurate for me. Being able to not spend 10 minutes making something I'm going to immediately unmake next time I use it and instead using that to read my AC/DC Fundamentals for my Mechatronics Engineering course has proven to be SUBSTANTIALLY more effective at bringing me success recently...

You act like there's NOTHING you could be doing in substitution, and that the person is going to be sitting there staring at a wall because they aren't making their bed. The bed has nothing to do with it, it's being productive with your time.
