Proposals and Stress = Check
low success rates and intense competition = Check
Need for sales = Check
I can't help but think you essentially have the same situation in academia as one has in a startup, only "it's different." The difference to me is the illusion of control. One may think that they are in control of the startup vs. the bureaucracy of government/academia/established business.
I posit that most things that are required by business are, in fact, not under your control. The illusion of control is there and one may feel that actions are leading to certain outcomes, but the truth is they have no direct control of the outcome. "Luck" plays the same role in the bureaucratic or private enterprise affair... some have it and others don't.
