Solitude is the state of being alone without being lonely. It is a positive and constructive state of engagement with oneself. Solitude is a time that can be used for reflection, inner searching or growth or enjoyment of some kind. Deep reading requires solitude, so does experiencing the beauty of nature.
Solitude frees the mind up from all the distractions of everyday life and allows it to focus more fully on one thing. It allows your brain to think outside the box and to come up with unique, extraordinary solutions to ordinary problems.
