That's what my aunt always say...you have to treat yourself well, especially spiritually...when you think of crap, it's always going to come back to you at a later date. And it isn't very easy to throw those stuff away...
For me the answer to most of these bad situations is "can I fix it?" and if the answer is no, leave that and do something better :D You don't waste time when you only have one life...
That's awesome @lilacse. I've tried to teach that to my kids. I didn't learn it until recently, so we're having to throw away a lot of things when they come up.
