Sometimes we need to be alone, to simply do nothing but enjoy the sound of silence.
Yet, too much isolation, especially when our intention is to hide, withdraw, or not deal with the realities of our lives is not physically, mentally, or spiritually healthy. It is during moments like these when being in isolation takes us away from our lives, rather than enhancing it. If anything, too much isolation can create a buffer whereby we don't have to deal with our problems. Sometimes, pushing ourselves to deal with our issues and be in our lives, rather than isolate, is one of the best gifts we can give to ourselves.
Also, just as it is important for us to have our "alone" time, we need to remember that as human beings, we are by nature social creatures that thrive on human contact. Our lives cannot occur in a vacuum, and we cannot fully live in this world without interacting with others. Consider using isolation as time spent for rest, reinvigoration, and personal growth. Isolation can then not only empower you, but it can allow you to return to your work and your relationships restored and ready for life.
