Although the Chicago weather might encourage us to pretend it’s still summer, today we enter the season of autumn. Trees are slowly turning gold and we can sense the days shortening. I see this as a time of great opportunity. To me, it almost makes more sense to set a goal to give something up at this time of year, rather than on January 1. We can take inspiration from the natural world:When the days begin to shorten in the fall, a tree responds to the lessening of sunlight and cuts off circulation to its leaves, pulling back its resources to the essential trunk and roots. The leaves dry up and fall away, and as they return to the earth they enrich the soil the tree grows from. In this way the tree survives the short, cold days of winter. It can reproduce its foliage in the spring, when once again resources will be abundant.The tree is a metaphor, but our bodies go through a similar transition. In my practice I talk with my patients about their feelings at this time of year. Many people notice a turning-inward, an inclination to hibernation, or a desire to snuggle up at home with warm carbs. We can all understand the impulse to sleep earlier and be a little less social when the days are short. These feelings are natural because our bodies are part of nature. We don't need to fight them, and in fact I would suggest we embrace them. There is opportunity here that I invite you not to pass up.With shorter days comes more time for introspection and possibly self-improvement. We all have things we hold on to that no longer serve us. Whether it is a grudge, old clothes, a habit, or a hairstyle, the autumn energy can inspire us to release the old to make way for the new. As these things fall away, we may be able to see more clearly the path to further growth. Maybe take a minute today to write down a few goals for the fall season, harnessing the potential of this time. Think of it as the start of a new era, rather than the end of an old.
