the easiest way imo is to replace it with something else
i basically replaced com games with lots of work and sex and
going out when im not working.
stare at my com /laptop/phone 20 hours doin work, i hardly
wasted time on any game this year, the most once a month with
friends at lan
remember money is more impt than games and then when your
actually making money you can freely do anything else you want
too
for now you can get yourself a hot girl you like being with more
than wasting time playing l4d for the 1000th time, and spend time
with her and other good friends instead
*i used to be lvl 40 warcraft tft solo and audition. and i
completed every final fantasy. but i lost an amazing girlfriend of
3 years because i spend more of my free time playing com games and
neglect her. that made me realise i was a immature useless piece of
shit and stop playing games.
