Repetitive
In sporting endeavours, repetition is important for skills improvement, so repetitive drills are undertaken. Same with musical pursuits: scales on the piano, breathing drills for the flute.
There isn’t an equivalent for knowledge work. In fact, most knowledge work prides itself on its uniqueness each day, the variety, ‘every project is different’. And yet, having repeatable skills in some parts of knowledge work, bedded in, coming instinctively and without pause, might just make knowledge endeavours that much more satisfying. Something similar to mastering a complicated piece of music or outsmarting the opponent in your soccer (football) game with fancy footwork.
