A few posts (on Motivation, Learning, and Perspectives) from a few days ago were also an experiment. They all pointed to the James Clear newsletter to see whether anyone signed up through those referral links.
James had offered some bonus material if at least 3 people signed up through those links. Being lazy to use 3 additional email addresses to get the bonus material by myself, I wrote these articles to see whether others would bite. On top of my newsletter, this was also posted on LinkedIn and garnered over 500 views in all.
No one signed up. Zilch. Nada. And I did proceed this afternoon to use 3 of my own emails to satisfy the curiosity (FOMO?) of what these additional materials contained. Nothing much really there of significance, but that was not the point.
