I really enjoyed the information on perspective, evaluating our beliefs about adversity, and focusing on having an internal locus of cotrol. In regards to taking control of one's own health to reduce stress, the simple changes that could be implemented in each of the 4 areas, nutrition, sleep, exercise, and meditation, might best be tackled one, 21-day challenge at a time, so that you don't feel like you have to improve or change everything all at once. I've really been focusing on this over the past several months since the Covid-19 pandemic created so much added stress to all of our lives, and especially those like myself who work in healthcare. I started just by simply trying to go for a walk for 15 to 20 minutes each day for 21 days. The next month, I continued with walking and tried to reduce the amount of sugar in my diet for 21 days, and so on and so forth, until I found that I was able to develop healthy habits in many areas over a period of time. When we try to tackle all areas at once, it becomes overwhelming, and then we are much more likely to give up before we can sufficiently develop the habit.
