In my opinion, people are easily addicted to gaming because of the instant rewards that it gave them. The dopamine release is quick and there's so many of them when playing video games. However, other things can also give us rewards. For example, exercises give you the rewards of health, but not as quick as playing games, because you have to be consistent in your exercises, and maybe you'll feel the rewards months after you started. Learning a programming language, or video editing will give you the rewards of money, but not that quick, because you have to be consistent in building the skills needed to get a job, or build your own business from that. Maybe it will take months, or years after you started.
My point is, when you want to quit gaming and direct your mind to other things, think about the rewards that they will give you. The money from programming skills, or the health from doing exercises, just know that you won't get the rewards as quick as playing games.
Hope this helps.
