I've been thinking about what you said. It seems like you are saying that the 180 thing is a matter of trying different things and observing what works. And then to keep doing that. And then to keep adding on other things that work.
I guess this is something that I've not really thought about conciously. This is a process, and I'm looking for a combination of things that work , rather than the 'one' thing. When I hit the right combination the vault will open.
