Un bel pezzo su Leonardo lo trovate sul chronicle :
If creative procrastination, selectively applied, prevented Leonardo from finishing a few commissions — of minor importance when one is struggling with the inner workings of the cosmos — then only someone who is a complete captive of the modern cult of productive mediocrity that pervades the workplace, particularly in academe, could fault him for it.
Productive mediocrity requires discipline of an ordinary kind. It is safe and threatens no one. Nothing will be changed by mediocrity; mediocrity is completely predictable. It doesn’t make the powerful and self-satisfied feel insecure. It doesn’t require freedom, because it doesn’t do anything unexpected. Mediocrity is the opposite of what we call “genius.” Mediocrity gets perfectly mundane things done on time. But genius is uncontrolled and uncontrollable. You cannot produce a work of genius according to a schedule or an outline. As Leonardo knew, it happens through random insights resulting from unforeseen combinations. Genius is inherently outside the realm of known disciplines and linear career paths. Mediocrity does exactly what it’s told, like the docile factory workers envisioned by Frederick Winslow Taylor.
Leonardo inseguiva in maniera costante le sue passioni e la priorità con cui seguiva i progetti non era dettata dalla commissione o dal lavoro che stava svolgendo, bensì dal suo interesse momentaneo. E finiva pochissime cose, quasi nulla. Ma ne iniziava tantissime.
