As a parent of an adult gaming poster-child I do understand. It's always a case of hind sight. I learned to regret letting my kids have too much access to video games. My middle child continues to pay the price. Zero ambition while 100% self serving. My wife and I have had a rough 12 years with him. He is now 30 and lives in one of our rental properties. He didn't want independence with responsibilities.like paying for his support. For years, he has thought that his money is for his entertainment only and resents paying for things like rent/food/utilities. He is somewhat responsible in that he keeps his jobs for about a 12 month avg, before moving on to something else. Lately his mom manages his finances, so he is paying some of his essentials. Slow progress, but it's is progress non-the-less.
Our solution to finally get him off the couch at age 24 was remove and forbid any video games in our home. I blocked internet asses after 9pm and eventually blocked all internet access for his pc at our firewall. He fussed, cussed and finally blew up after about 4 months. Telling us that his lack of ambition and misuse of us was our fault. My wife and I realized he was right. We had to take a much harder stance with him. He got a job which he has more or less kept and now lives with his girl friend.
Needless to say, it has been a long a painful process. He still doesn't have any long term ambition or desire to do anything beyond work hours except entertainment activities. Simple things like cleaning and maintaining his living space are still beyond him, but,....hope springs eternal eh?
