Going through our lives, we might be able to arrange things so we can have a series of good experiences, maintaining the outside world in a careful balance, so it seems like we are happy.
In some ways, this is dysfunctional, and in an extreme case, it is the attitude of a drug addict. They arrange things so they can get another fix, and feel satisfied. Soon after, they have another lack.
We might believe that our good experiences fulfill us, but perhaps we are merely avoiding dissatisfaction.
If we look deep inside, we might find we don’t really need to do things or receive things. All we need is our own support, being our own best friend.
