I'm POSITIVE!!!

I've been reading a lot of self-help type books lately--And trying to be more positive about life and how I view things. I'm not a very outgoing person,so I'm taking small steps every day. I just really value my quiet time too much! Does that sound selfish??? Positive does bring positive--I notice how differently people react towards me when I put out the effort to laugh more and smile....(But I CRAVE being alone!!) I'm TRYING!!!!!
