A learning experience through trial and error is a common recurrence in nearly every creative venture. The acquisition and perfection of technique is only achieved through endless refinement during hours of practice. Learning is so deeply embedded in these activities that renowned magician Teller defined his profession simply as 'someone spending more time on something than anyone else might reasonably expect'.
And yet this process is rarely seen in its entirety. To learn a magic trick, to develop a painting technique, to 'git gud' at playing videogames, it all requires many fragmented practice sessions, with breakthroughs during some and setbacks during others. Because of this fragmentation, where time spent not practicing is as important as practice itself, capturing the full process with all its intricacies is nearly impossible. Like other kinds of movement, it can easily be summarised, but it's extremely difficult to show in full. The closest anyone ever seems to get is a Rocky-style montage or vignettes that merely show a single part of the whole trajectory.
Partly for this reason, the importance and omnipresence of learning through trial and error is often underestimated or not well understood by the casual viewer.
