Consistency

It's the answer to the question: what's the common quality needed for living both i) a healthy life and ii) your calling?

These are not one off projects, thus it's a bit more difficult to set concrete goals for them. But they can be done.

The challenge is to consistently take care of these aspects in life. To put in the efforts, to pay the price. These are important, long term benefits, requiring you to consistently work on them without an exciting picture in mind and only occasional emotional stimulants.

So? the conclusion?

Habits.
