I had the same epiphany early in 2013. Feels good, most of the time. I do sometimes wish I could spend a straight week getting mashed and playing games though. Seeing my PS4 and XBone backlog sitting there kills me sometimes. As you said though, that's what retirement is for.I think I just had an ephinany when I moved to Manchester about how much of my life I've wasted sitting on the sofa stoned watching TV and playing video games. I was scared of looking back when I'm 40 and thinking "wow, you really did fuck all with your life didn't you". You've got the rest of your life to be a couch potato, that's what retirement is for!
In the last 9 months I've sold most of my blurays, three consoles and a fuck load of games. I now have like 20 blurays, a PS4 and 5 games. I barely touch my PS4 and I don't watch anywhere near as much telly as I used to.
I just don't have the time anymore, my priorities have changed.
...man I miss weed.
