Good thing I didn’t read such a bullshit defeatist conclusion before I dropped 40 lbs 7 years ago (adopted sane diet, never gained it back) and dug myself out of a deep hole of alcohol dependence. haven’t beaten the habit of falling for engagement baiting headlines though i suppose do not let yourself believe you are weak or a victim
the TLDR of the article is that if you (for example) are struggling with focus, a strategy that is basically telling yourself to focus (while loud music is playing around you) will not yield as much success as removing distractions (turning off the music) in your environment, then trying to focus again.
the efficacy of the two strategies is dependent not entirely on ones fortitude, rather ability to craft an environment that plays to the strength of will, so to speak.
