Agassi's Halfway turning point does what all good Halfway turning points do: signals a move from ambivalence to commitment. At that point, as Agassi quickly finds out, rather than get better, the Halfway point signals that things are about to get way worse.
The writer / protagonist (today's on-going plot consultation illustrates how closely the two are tied) leaves the ordinary world when she signs up for a series of on-going plot consultations with the goal of finishing a writing project she has started and stopped for years.
She slips into the writers life with ease. Fortunate to have a lifestyle that supports writing and reading and fully sinking into the writers life, she sets up a dream writing schedule. Every morning, write with coffee. Write and walk. Write and errands. Write and eat. Write and read. Write and sleep. Sounds heavenly. Only distractions are those she allows.
Yesterday she hits the wall. Comes up with two new writing projects in quick succession. Retires to bed sick. Rejects vision of literary genius.
She hits the exact same point in her writer's journey that the protagonist is about to encounter on the hero's journey. Up until now, the writer and the protagonist have gone through the motions. Now, with full commitment, the writer and protagonist step forward thinking that by making the commitment, the hard work is behind them. They step forward into thin air without a clue that the worst is yet to come...
Crank up the energy. Next is the Crisis...
