keep digging into where you first got those messages, those old tapes. in the meantime, you can challenge them when they come up. you say STOP, what you are saying is not TRUE and i will not listen.
and then you start going out into the world with less STUFF, more YOU...for as long as you can take. you listen and observe and you begin to realize nobody gives a sh!t. nobody CARES what brand of whatever YOU have...because they are obsessed with what THEY have.
and maybe consider downsizing. if you have too many clothes to fit in the closet, you have too many clothes. and they serve you no purpose. they become part of the LIE.
they do you NO good stashed away. that's called hoarding. we can make it this as hard or as easy as we wish. we can come up with excuses or we can plow ahead. depends on how eager we are to get to the other side.
