I think this is about self inventory.
Everyday, look at where you place your priorities. WHo is taking up the most of your mental real estate?
And start taking it back, a little everyday, and pat yourself on the back, and learn to love taking care of YOU.
Its hard.
Also, Its important to remember that its about progress not perfection.
It is similar to alcohol recovery, I guess, but, not quantified by days clear of putting someone elses in place of your self presence.More by feeling out where your attention is, and if you are living for yourself, in the moment, instead of drifting over to what "they " are up to...whether "they" are doing the right or wrong thing...
Just keep pulling your eyes back to your own homework, it becomes a habit.
I am not an expert at it, BTW, but, a work in progress, LOL...
Keep posting!
