A yoga teacher once told me: practice really starts to change once you do it three to four times per week. It’s a general threshold to more meaningful results, and a point to consider more broadly. What is the input necessary to get our desired output? When can we expect to see a difference? Is there a minimum effective dose? Some things won’t change until we reach a certain threshold, some things are impacted by thresholds of others (see Granovetter’s model and Malcolm Gladwell), some things require maintenance to stay within a threshold, and some things might even be irreversible after reaching a certain threshold. It helps to know what moves the elevator.
