This is a very deep video. This man lost his family because of his hobby, and shares the experience and gives some very important advice. A person doesn't have to be married with children to get something out of this; anyone who has a strong passion for a hobby has relationships that are important, whether it's immediate family, or friends.
NOTE: This isn't anyone affiliated with the blog (or even chess as far as I know) but it's a powerful video nonetheless. The man who created the video has his YouTube channel located HERE.
