It is all in this quote,
You will never be happy if you continue to search for what happiness consists of. You will never live if you are looking for the meaning of life – Albert Camus
..even worse, if someone does it in their own bubble and isolation, they are bound to create miscommunications and resentments in their relations with others, and problems for others as well. Worst of all, if their meaning of life makes them moralists which becomes even more irritating for others :p
Be thankful in whatever you get and thoughtful about what it entails, simple solution.
