When we accept the world the way it is, we become more effective in influencing ourselves and others to change in the direction we'd like. Develop skills in negotiation and compromise, and become more flexible in those areas that aren't so important to you. Demands are a major source of stress. Take relaxation breaks. If your schedule is busy, prioritize your activities and do the most important first.
