You have your reasons for doing things. And the purpose that you have behind your actions is probably quite significant. But don’t expect most people to understand your reasons.
Everyone has their own reasons for doing something. One person might go to the beach to get away from the city. Another person might go to the beach to be near crowds of people: the same beach, same day, different reasons. If you try to explain your reasons to each other, it often ends merely confusing the other person.
When you are explaining why you do something to another person, the best thing that you can do is tell it in a way that they can empathize with your reasons. They may not understand it rationally, but if they can feel the same thing that you do, then you have made a connection.
When someone is explaining their reasons to you, the best thing that you can do is to find the connection point. Don’t ask about details; ask about feelings. Ask about similar experiences. Understand the path that brought the other person here.
