Ben-Shalar uses three optimistic exercisers. When he feels down-sag, after giving a bad lecture-he grants himself permission to be human. He reminds himself that mot every lecture can be a Nobel winner; some will be less effective than others. Next is reconstruction, He analyzes the weak lecture, leaning lessons, for the future about what works and what doesn’t. Finally, there is perspective, which involves acknowledging that in the ground scheme of life, one lecture really doesn’t matter.
