7. Think good thoughts for others.

Maintaining a compassionate mindset is another way to conserve energy. One example of practicing this way of thinking is called kind attention. For example, try to make eye contact with a stranger and smile, while thinking "I wish you well." This positive act can, instead, keep you from judging that person. Judging others can cause us to place judgment on ourselves, and that type of negative internal dialogue can be exhausting.
