It’s important for you to devote some serious energy to finding a balance between your internal life and external life. You may be depriving yourself of the attention you need to be happier. Having fun is a perfectly fine thing to do, but you shouldn’t be doing it 24/7. If you feel that strong of a need to goof off, you might be trying to avoid dealing with something you need to face. Spend some quiet time and get back in touch with yourself.
