Step out your boundary and try something new; it's OK to switch things up every once in a while. If you are used to being to yourself, try going to a friend's party, seminar of your interest( I'll be going to my first seminar on digital photography today!), or any other social event to get you out there. If you're bored, try a new sport or get that guitar that you've been thinking about and wanted to play, or try the new restaurant down the street that everyone's talking about. In all, just be open to new possibilities and not do the same routine you've been doing for 5 years now. You'll never know, you might be happy you tried it.
