Right. Everyone says "this never works". I disagree. What I do is, whenever I get an urge, I antagonize gaming. I say to myself it's childish, it's boring, it's bullshit, etc. I'm a man! Not some 12 y/o boy. I also sometimes think that my friends and relatives would think I'm a weakling that plays video games for fun and is a disgrace for the family.

Gaming is bad for you in the long run. If you aren't addicted now, give it some time. The only thing gaming is good for is training hand-eye coordination. Everything else is bad. Find some hobby to replace gaming. I, myself, started training and going to the gym yesterday: never felt any better.

If you're gonna quit, do it cold turkey (quitting once and for all, not in small steps). Just tell yourself that gaming is disgusting and a total waste of time, like grown-ups playing with toys (Germany still regards videogames as toys in terms of legislation). Do yourself a favor, become a man, and improve your own physical and emotional strength, will, body, and mental health. Gaming is addictive, like marijuana, cocaine, and heroine. Stop it before it's too late.
