Question: is this a 2) strong advice, 1) weak advice 0) no advice?

This result is consistent with empirical evidence from the “Strength Model” of motivation (Hagger, Wood, & Stiff, 2010) and the concept of “cessation fatigue” (Liu, Li, Lanza, Vasilenko, & Piper, 2013), both of which posit individuals have a finite amount of “energy” for self-regulation and predict that repeated failures should result in less motivation.
