"The more time and effort that people put into anything - no matter how useless, dysfunctional, or downright stupid it may be - the harder it is for them to walk away... We all justify the time, effort, suffering, and years and years that we devote to something by telling ourselves and others that there must be something worthwhile and important about it or we never would have sunk so much of our lives into it."
- Robert Sutton, PhD (The No Asshole Rule)
Excellent stuff and great advice for people who trudge along for months or even years using the same system, split, routine, diet, scam, or scheme, waiting for their progress to, at some point, suddenly take off. Understand, I'm not talking about consistency here. I'm talking about blind adherence to a program despite a preponderance of evidence that it isn't meeting your needs.
