What you do when everything that you invested as plan A falls apart? Like say, building a spaceship that travels at half the speed of light to reach the nearest habitable solar planet in 120 years. And, as engineers know, you build several backup systems for the systems you use in your ship. Except there's no backup ship. So the only plan B when you reach that point in space is that, perhaps, there should not have been a plan A in the first space^H^H^H^H^H place. Except if you remained in the place where you duct-taped your plan A, there wouldn't have been a plan B either. Or C. As a trader, I'm not planning for A but, worst case worst, if I rotate and get back to -1. And then, I improvise.
