I think it’s really helpful to be in a position where your life is filled with lots of wonderful things that bring you joy to the point where your cup of joy runs over.
The alternative is for your life to be filled with a single wonderful thing that brings you joy.
The problem with this is that if that one thing goes away, your whole life will feel as though it’s falling apart.
It’s like that saying about not putting all your eggs in one basket.
This can be applied to many aspects of life. For example when a person attaches their whole identity and sense of self to their career, if they get made redundant they suddenly feel like they don’t even know themselves.
However, if you perceive your identity to be made up of multiple aspects then even if one of them changes or goes away their is still a bigger part of you that remains.
