Is gratefulness a habit or mindset? Do we call it a habit just to cultivate that mindset in long term?

I think gratefulness is a ever accessible state of being we practice the habit of shifting into regularly in order to strengthen our connection to that state. So I agree with the statement implicit in this question.

I think it’s a mindset,it may be a habit in the begining of way but eventually it’ll become a lifestyle.
When you look at old people,specially in my culture they are just happy with what they have.
