... in order to continue Deanna's conversation with her parents. It did look like something of a breakthrough was happening.

Well, maybe not quite the breakthrough they were hoping for.
Yes, this on-the-edge obsession of Deanna to make Mike a success is my tribute to the "small sewing school" future in the Strip of Destiny, which clearly wasn't going to work unless Mike could support the family himself. It hasn't occurred to Deanna that she might not feel work was such a drudgery if she weren't run ragged doing
everything so that Mike is left free of all responsibilities except his muse.
Wilf clearly has his own ideas of the root of this obsession.
Either way, Deanna is doing everything, because while freelance writers complete projects on their own time, Mike has been given a ton with hard-to-schedule subjects.
(Maybe he's annoyed people in the industry?) And it looks like Mike has neither been asked to nor has he figured out on his own to use the rest of his time wisely.
