Solitude is a good way to find oneself. When we are always with people, we tend to disappear in their personalities, we blend in, we lose touch of our own identity. Sometimes we make decisions not because we want to do them but because that is what people (friends, family, even our enemies) expect us to do. Being in solitude, excluding yourself from the world, gives you the chance to rediscover yourself, to rediscover what you really want in life without anyone telling you what you should do, what you should feel. It gives you a sense of peace, gives you space to breathe, away from all the stress life gives us. People should be with themselves from time to time so they can recharge.
