Modern people have lost the art of hosting, being a community member, and inconveniencing themselves. Throw the party. Host your relatives. Ask the person on a date. Treat your friends to dinner. Learn to cook for others. Meet your neighbors. Talk to the person at the grocery

The whole “it takes 21 days to form a new habit”… is false. the data say 7 to 200+ days. Even with consistency. Depends much on how well you manage what I call limbic friction (not a technical term). The solution is easy. Explained here. 30 min episode.
