If you work at home alone and you need human interaction, get a dog. It will force you to get outside and interact with humans.

I met a young person once who was successful (multi-millionaire) and had sold several companies. In the post-sell lull, he said that until he got a dog - he didn't have a daily routine - since he didn't have to really work. Showering is a habit that quickly can fall by the wayside if you work from home alone too much.
