And that's exactly the point - you'll very quickly lose your passion for something that you're "obliged" to do. Explaining that in the easier terms - it's like fapping. It's nice, relaxing and you're passionate about it - but try doing that 8 times per day 5 days per week. In just a few weeks (maybe even days) you'll start hating it and in a few months you'll become impotent (unless you're some kind of superhuman and the uncontrollable fapping is your raison d'etre).But I would assume you choose to work on a game because it's your passion? The normal daytime job often is just something you gotta do to pay your bills but if you can make money out of something you love (creating games) I'd say it should even boost the motivation and workflow...
