If what causes you stress is something you can avoid, then go for it! Unfortunately, most of what we find stressful is perceived that way because we can't avoid it. While you may not be able to avoid stressors, you most certainly can change how you react to them.
Try to consider that every human experience has a positive and negative aspect, depending upon your perception. Whether we judge an event as uplifting, healing, rejuvenating or depressing, enervating, or disease-promoting, depends on the spin we give it. Illnesses, emotional challenges, insults, and accidents all hold the power for change, re-evaluation, and rejuvenation, if we will only look for them.
