Many people bring up the positivity of quitting, or minimizing, social media. The same thing could be extended to gaming.
I have quit social media, only using twitter to follow my interests, and quit gaming back in high school. Both of which took many, many weeks away from my life.
I am amazed at how much time I have outside of work compared to my peers that are hooked on social media or gaming!
All that being said, neither are evil, and both can be fun, but for many people they silently rob you of precious time, and peace.
It helps to view things not on a micro, hours per day, scale, but on a lifetime scale. 2 hours gaming daily, 5 times a week, from age 10-30 is well over a YEAR of your life! Now consider the binge gaming phases of life and it certainly takes a lot shorter of a time to hit 1 year.
