The two minute rule is simple: if a task takes less than two minutes, do it immediately. The idea is that once you start doing something—even a tiny action—it's easier to continue doing it.
For example, if your goal is to read more, start by reading just one page. If you want to exercise more, start by doing just one push-up.
The act of starting is often the hardest part, and this rule helps you overcome that initial inertia. Over time, these small starts can lead to the development of bigger, more established habits.
