“…Greater well-being was related to spending less time alone and more time talking to others: The happiest participants spent 25% less time alone and 70% more time talking than the unhappiest participants.

In addition to the difference in the amount of social interactions happy and unhappy people had, there was also a difference in the types of conversations they took part in:

The happiest participants had twice as many substantive conversations and one third as much small talk as the unhappiest participants.”
