A wandering mind, then, is an unhappy mind. If you can focus on your day-to-day tasks and save your daydreaming for when you choose, you will be able to cope with the sorts of stress that earthquake victims suffer much better than if you are a mind wanderer. Resilience then, needs focus. If you keep your mind on the moment-to-moment tasks of ordinary life, you’ll shield yourself from extra stress which saps your energy and hence your strength.
