Hey there!
Erik Erikson developed and proposed 8 p<span>sychosocial stages of life. These, in order, are trust vs. mistrust, autonomy vs. shame, initiative vs. guilt, industry vs. inferiority, ego identity vs. role confusion, intimacy vs. isolation, generativity vs. stagnation, and ego integrity vs. despair.
It sounds like the last one, ego integrity vs. despair, is described in your problem. The last stage begins around maturity, or 65, and goes on until death. At this stage, people are often retiring or are retired, and start pondering the things they didn't do with their lives. This leads to regret about not doing certain things that they once hoped to do, or maybe didn't even realize they wanted to do at the time. They think that it's too late now, and start feeling dissatisfied with their life, as your question describes.
Hope this helped you out! :-)</span>

Answer:
You could include Herbert's Simon's satisficing and Amos Tversky's elimination-by-aspect heuristic rules.
From Satisficing strategy, you must decide which are your goals, what do you want to achieve through social invitations.
By doing this, you are setting an aspiration level. Then, you choose the alternative that satisfies your aspiration.
On the other hand, you can use elimination-by-aspects heuristic strategy to reduce the number of alternatives that do not meet the aspiration level.
