You don’t have to be a “holdout,” because the energy comes from all around you. You do not hold it within; rather, you breathe it in through your mouth and nose and drink in the beauty through your eyes and absorb the sun through your pores, and then exhale and return all the energy back to its source for replenishing.
You, also, are the source. You are responsible for replenishing other’s energy that they breathe out to you. So don’t conserve your energy, because there is an unlimited supply source all around you.
