As far as I can tell, the only mistake Lisa made was at the Habitat for Humanity house when she said she thought she was better at motivating other people to do the actual work.
The mistake was that she thought she was manipulating Allison successfully into making like her personal maid, and that it represented a talent that applied to other people - a mistake the other ladies were quick to point out at the house. It doesn't require anything at all to get people pleasers to go for the look-good. That's just what performers do. The drama serves well to highlight all that looking good, doesn't it? This one just can't decide which script she's reading from.
All "inspired" in Houston, "victim no more" at the beach, whining all night because it wasn't all about her at the SOH when she got back. I see the attraction, though. Lisa gave her max opportunities to do the look-good, and she gave Lisa free maid service. I think they call that...symbiosis.
