Many of the commenters protested. As one reader asked: “Unless you’re actually having fun [with your work], why do it?” I think these commenters are worried about the conclusion that work should create suffering. Here’s the thing: I agree with their concerns, and this was not the point I was trying to make

This is why choosing an external system that forces us todeliberate practice and confronts us as much as possible with ourlack of understanding or not-yet-learned information is such a smartmove.

I rolled back your edit because the double negative was very deliberate - I explicitly would not claim correctness, just lack of clear incorrectness

An adviser should have their students explicitly practice decisions 25 and 26, test their solutions, and try to come up with the ways their decisions could fail, including alternative conclusions that are not the findings that they were hoping for. Thinking of such failure modes is something that even many experienced physicists are not very good at, but our research has shown that it can be readily learned with practice.

which often come into my mind ‘out of the blue’ rather than deliberate intent.

Generally speaking, it would not be a good way to express something in formal writing, unless perhaps you were deliberately injecting humor.

Van Breda Kolff says that Bradley is “a great mover,” and points out that the basis of all these maneuvers is footwork. Bradley has spent hundreds of hours merely rehearsing the choreography of the game—shifting his feet in the same patterns again and again, until they have worn into his motor subconscious. “The average basketball player only likes to play basketball,” van Breda Kolff says. “When he’s left to himself, all he wants to do is get a two-on-two or a three-on-three going. Bradley practices techniques, making himself learn and improve instead of merely having fun.”

His jump shot, for example, has had two principal influences. One is Jerry West, who has one of the best jumpers in basketball. At a summer basketball camp in Missouri some years ago, West told Bradley that he always gives an extra hard bounce to the last dribble before a jump shot, since this seems to catapult him to added height. Bradley has been doing that ever since. Terry Dischinger, of the Detroit Pistons, has told Bradley that he always slams his foot to the floor on the last step before a jump shot, because this stops his momentum and thus prevents drift. Drifting while aloft is the mark of a sloppy jump shot. Bradley’s graceful hook shot is a masterpiece of eclecticism. It consists of the high-lifted knee of the Los Angeles Lakers’ Darrall Imhoff, the arms of Bill Russell, of the Boston Celtics, who extends his idle hand far under his shooting arm and thus magically stabilizes the shot, and the general corporeal form of Kentucky’s Cotton Nash, a rookie this year with the Lakers. Bradley carries his analyses of shots further than merely identifying them with pieces of other people. “There arc five parts to the hook shot,” he explains to anyone who asks. As he continues, he picks up a ball and stands about eighteen feet from a basket. “Crouch,” he says, crouching, and goes on to demonstrate the other moves. “Turn your head to look for the basket, step, kick, follow through with your arms.” Once, as he was explaining this to me, the ball curled around the rim and failed to go in.

Ericsson claims (2016, p. 98) that there is no deliberate practice possible for knowledge work because there are no objective criteria (so, poor feedback), because the skills aren’t clearly defined, and because techniques for focused skill improvement in these domains aren’t known.

The main matters on which all men deliberate and on which political speakers make speeches are some five in number: ways and means, war and peace, national defence, imports and exports, and legislation.

Not all voluntary acts are deliberate, but all deliberate acts are conscious -- no one is ignorant of what he deliberately intends.)

Again, that is good which has been distinguished by the favour of a discerning or virtuous man or woman, as Odysseus was distinguished by Athena, Helen by Theseus, Paris by the goddesses, and Achilles by Homer. And, generally speaking, all things are good which men deliberately choose to do; this will include the things already mentioned, and also whatever may be bad for their enemies or good for their friends, and at the same time practicable. Things are "practicable" in two senses: (1) it is possible to do them, (2) it is easy to do them.
