Why can't I play video games without getting completely obsessed?

I really don't play video games that often. But whenever I do, I tend to get addicted and obsessed with whatever game I'm playing rather quickly. Particularly with the game Minecraft. At one point in my life, I was basically playing Minecraft for over 10 hours a day. And the scary thing is, once I get wrapped up in playing games, hours fly by, and before I know it, the game becomes my top priority. I quit playing video games, because I'm convinced that my mind doesn't have the ability to play video games in moderation. I'm just not wired like that. I'm like that with everything… Music, movies, writing, art, etc. When I find enjoyment out of something, I push it to the ultimate limit. There are no middle grounds, if you get what I'm saying. So overall, I simply don't play video games, or Minecraft anymore, because I know how addicting they can be for a person like me. I know that sounds lame. But it's the truth.

How do you use the Teleport Command in Minecraft?

I have tried to use this ******* command 4 times and it doesn't work. I've tried to use the stupid block but for some reason that doesn't either and I have tired to look for the folder to enable it but google wasn't helpful and neither was Planet Minecraft. I don't want to use the command block. I just don't like it.
Can anyone please help?
