Some hobbies are much harder to do than others. For those, the doing will be a lot less than the discussing. Examples, scuba but don't live close to water, flying, but can't afford to do it frequently, etc.
Also, the ability to "do" a hobby might vary over time, depending on many factors. Some are season-related, others might depend on personal life or even health. This might shift the hobby execution between the quadrants.
