The talk I gave yesterday, that my advisor and I were both so proud of, was something of a precursor to my dissertation proposal. I presented on the only truly successful research of my graduate career, two experiments that are the first two experiments in my proposal. I also presented a conceptual summary of what I have planned for the next experiment.
The upside is that it was an incredibly successful talk. Two other members of my dissertation committee were there, asking questions and making suggestions, and both of them complimented me on the talk afterwards. I have a brief preview of what I might have to deal with in convincing them to approve my dissertation.
The downside is that there were lots of suggestions on what I should do instead of what I had planned to do, so I am revising my proposal, again. I consider myself extremely fortunate that two of the experiments have already been completed, so I only have to revamp two of the experiments at the fancy of my various committee members.
At least there's plenty of time to revise the proposal. One of my committee members could only be on my committee if the proposal were between May 7th and May 12th. This gives me a free pass to avoid the official "by [the end of] April" deadline, and several extra weeks to change the proposed experiments three or four time at my advisor's suggestion, before giving it to the committee so they can propose another three or four rounds of changes.
But I can't worry about all this now. Tomorrow marks the first day of the conference, in the "pre-conference" activities. Let four days of carefully controlled chaos commence...
