That’s why I keep saying, look for new sources of psychological energy. You can find them in the most unexpected places if you let yourself notice what the real you, and not the version you think you should be, enjoys.
It can be absolutely anything. Twenty years ago, I derived enormous supplies of psychic energy from the paper napkins at a certain location of the Van Houtte coffee shop chain. I would clutch a napkin, and it would make me feel goooood. It was like plugging into a source of energy right there.
Ideally, you make a list of these little energy-giving activities, and then whenever you feel depleted just go through the list and get recharged. These are supposed to be easily accessible activities that you can do any time. A vacation in the Caribbean or a stroll through Madrid would have an enormous effect, but you can’t do that often enough for it to be a reliable energy source.
