Trying to do things too early creates eddy currents that will be 10x more energy than slow and steady moving through the iterative adjacent possible.
When you do things at the right time, it's just a matter of calm and steady progress.
When you do things too early, you constantly do the First 90 % and then don't do the Second 90% before you do the next chunk of First 90% work.
Good progress optically but on an increasingly over a levered base: a supercritical state underneath.
The First 90% creates upside.
The Second 90% caps downside.
Even supercritical states don't have disasters... until they do.
The Second 90% reduces the rate of disaster which is hidden, which means it will be under-invested in.
