Robert, thanks for you answer. Really appreciate it.
Things that make me consider going back:
Not wanting to fall behind in some games. If I ever want to come back, it will be that much harder & expensive.
Its easier to imagine the fun I could be having than the potential expected value I could get from other alternatives that I will have to work hard to succeed in.
Boredom.
If I nuke everything, I might never enjoy some of those unexplored and much praised games. Really good ones. Some of them I've looked forward to for a while.
I can definitely see some parallels to Jason's story (link 1). I could do the detox and move all the install files to an unused hard drive but that would be my closet that might trip me up in the future. The sunk cost fallacy link does make it clear that all of my 'reasons' are in fact emotions. How do you go from sitting with these feelings, there's no 'reasoning' with them, to action even if it feels bad?
I guess one of my fears is I'll wake up in 30 years (and I'm already getting there in age) and still be treading water getting nowhere. But I also fear its too late anyway. Yes, we like to say its never too late, but surely, for some of us it has to be. I suppose you could say I no longer believe some of my more ambitions dreams. In once case when I was asked to imagine any future with any possibility, I still went for the bleakest one.
Rereading that, I have to say thanks again. I usually say to myself I can think these things through but having to engage in a conversation brings something different out that I would have missed.
