One thing that I can say for sure, is that being alone at any given time makes you think. And not just "Oh wonder what I'll make for dinner..." it's usually along the lines of "I wonder if so and so is still mad about that time...". You really begin to think over things that maybe should be forgotten, or something that may never come to pass. All this wondering and daydreaming can be as beneficial as it can be detrimental. It's certainly good to dream and hope for things, but too much will leave you disappointed with the real world.
