"If you don't want to do something, one excuse is as good as another."
The only thing to do with such people is to listen and smile and wish them well. Their life, as it stands, is serving them in some way that we cannot understand, and perhaps they can't either, but the bottom line truth is that they are not ready to take the first step out of the bog they're in.
Change is always possible if we want it badly enough. The only real place we are stuck is in our minds.
I stop trying to help people that have no interest in self-improvement. I let them be and send them love. I have had times in my life when I wasn't willing to change either.
