Excellent point; once you're good at "ruining" or getting rid of stuff, the stuff you have doesn't bother you. The more you get rid of, the easier it gets, because you realize you don't regret any of it. Once you've got over the horror of throwing away valuable things yourself, you can exploit it in other people. "Hey, do you want...? If you don't, I'm just going to throw it away." Your stuff ends up in their closet instead of yours. You can also donate stuff to friends who enjoy having garage sales or selling at flea markets.
Bottom line, as with alcohol, there's no need to avoid it unless you know you can't handle it.
