Something that helps is to not make things absolute.
I haven't smoked tobacco in like 15 years, but I never quit, I just stopped !
I pretty much stopped smoking pot like 25 years ago, but will occasionally ( every few years) smoke a joint if someone breaks one out, then maybe not again for a few years .
I never quit or intended to quit.
Think of it in terms of stopping whatever your vice is, not flat out quitting .
I'm confident I'll never smoke another cigarette again, but I'd smoke some weed right now, it's probably been 5 years ?
