As a old time so-called "Independent/underground/experimental/new American Cinema/etc" filmmaker, at nearly 78 now, with 43 feature length films of all kinds (except remotely "commercial") I gotta say I loathe the filmmaker self-glorification of saying oh this is so so so hard and all the other bromides offered up. Filmmaking is no different than being a cook or a ditch-digger or bank teller or CEO. It is something you do. Perhaps because you want to, and maybe not. It is no more heroic or special than anything else.
