Well, I'd say it is both xD
My friends never(literally) do anything else than gaming or talking with GFs and I'm pretty fast bored, I can set myself up to saying: "I'm so gonna play this game and win a match!" and then 5 minutes after starting: "Nahh, this is boring! Let's see what else there is to play!"... This also includes making stuff, so if I end up not updating, I've probably lost interest...
