Applying perfection to transition into action is there to remember all the things that worked and that didn’t work as expected. Real perfection is to be kind with oneself when deciding into which basket to put the results found. There is no win in calling something radically honest to be able to put it into the failed basket.

None of the above perfection involves being perfect.
