>>1122978The dopamine thing is about the brain's reward system for doing things
Nowadays there are way too many sources of enjoyment where people do some simple activity and get some sort of reward and that messes with your brain chemistry
Games being a perfect example. They were already a gateway for this issue but it's gotten to the point where it's pretty much "press button, receive bacon". When your brain gets used to putting in a miniscule amount of effort to get a guaranteed reward it hinders your ability to get shit done in real life because getting somewhere in life more often than not is the result of putting in serious effort into something over a long period of time with no guarantee of reward
When you've been doing this for a long time it becomes increasingly harder to develop the mentality to succeed in life
Masturbation for guys is also troublesome for the same reason since your raison d'etre as a male boils down to coming inside as much pussy as possible, and our monkey brain can't really tell the difference between pictures on a screen and real women, so you're satiating your primal instincts without getting anything meaningful done and then you get accustomed to that and waste your life
