Well done.
I agree about the perils of the unknown after step four. But I'm perpetually in some degree of unknown. And some degree of fuckup, sometimes self imposed. I most always have embarked on a journey like this because the degree of fuckup was already a problem, and my post four problem is small by comparison.
Learning from my mistakes, sometimes repeated mistakes, is part of the pleasure I derive from such work.
Good job glatt.
