Yeah, I do get annoyed when I watch some of the DIY or renovation programs when they destroy stuff that could be preserved and either sold or donated to other people. I also get annoyed when they spend $ that they could use on essential things to decorate and stage the scene. Like Love It or List It. I see the designs and think: They could have redone that bathroom they took off the list if they had not purchased that fancy junk that is only decorative. I don't think I'd ever be able to turn my house over to a designer without being able to give input on details. I like Houzz and Polyvore because I can put together Ideabooks and even make a collage of ideas for rooms.
I do think that careful planning is essential. And always expect the unexpected. LOL.
