If you are not feeling as energized as usual today, the best remedy is to get with other people: preferably folks who have the big smiles on their faces. Being in a group environment will give you high energy and help you see where you fit in, where you belong. Any kind of group situation is good for you right now, from a crowded bus to a cocktail party. It doesn't matter what you're doing with others; it just matters that you are with others.
