Being sober for me is easy... By not being interested in alcohol to begin with, let alone build a habit around it.
However, abstaining from, say, sugar addiction? Guilty pleasures of screen time? Which is my kind of addiction.
Hmmm...
If I succeed, I wouldn't say I'll be proud of the so called accomplishment of unlearning crap, I'll just say I'm tired and wasted time and energy over having to deal with that...
And then wondering what to replace what with what. One would choose something like, say, exercising or something productive.
But no...
It's kinda like special interests -- sometimes it's not a choice, it's just something dropped on your lap.
And pray whatever what is being replaced with isn't another addiction in a different form to contend with.
