There were a few questions I should have thought about--how much more than she thought she could chew did she bite off? Did she have fall-back plans? How did she choose which larger-than-usual projects to take on? Unfortunately, I don't have any way to contact her.
As nearly as I can tell, I shut down my intuition( one of my more reliable faculties) because I wanted to try something bigger than usual that looked as though it would be profitable. On the other hand, going to Connecticon wasn't an obviously bad idea and I might have done it anyway--it just didn't work.
This doesn't mean I think my mistake was her fault, only that I need to be careful about advice. Even if it fits into someone else's life, it might not fit into mine.
