Human “limits” are the common points where people often decide to stop and give up. It is best to think of limits as the moment where you start to push really hard. The real fun starts at there.
I have to kick myself and sketch more of those.
You are never perfectly ready for anything, but you sense when the moment for action arrives; Then you do the necessary. In this world nobody waits for you to arrive at your foolish ideal of completion. You are “ready and done” when you are dead. Until then, while you still breathe, you are never ready. Non finito. Nothing is complete.
