When I get a movement right, I keep repeating it over and over until it's committed to memory. You're saying I could've stopped at the first success? Why did no one tell me earlier?

Nah. Some forms of practice like shooting or bowling or anything where the goal is to do something 10 or 100 times and get a high score are absolutely about doing exactly the same thing over and over again as predictably as possible and the variance of result is the problem.

If you don't like that example, how about chess puzzles?

Certainly between practice sessions you might wisely expose yourself to new ideas, but the idea is the same:

See a position, see the winning strategy / tactic / idea. If you're a student of the woodpecker method, once you do that once, you do it again, exactly the same way, and hope to be faster at it.

These are forms of practice wherein you do the same thing, exactly the same way, and hope to get increasingly better results by honing a skill through repetition without changing anything. its not that you CANT change things sometimes or that you shouldn't, but generally speaking the idea is consistency.

Ehh, I get what you’re saying but..that’s iteration, improvement, development

Practice is rehearsing the same move over and over, the phrase “practice like you play” exists for that reason. It is by definition, repetition.

Same is not identical.

"I am going to get a drink." - "I'm gonna do the same."

Will the second person now do identical movements to the first one? Will the second person use identical words to order an identical drink?

Or will both of them walk up to the bar and each of them will get some drink they like?

"I'm going to practice golf this weekend." - "Yeah, I'm going to do the same."

Will the second person immitate every movement of the first one? Or are both of them just going to practice golf, one of them maybe on a golf course and the other one on a drive range?

YOULL GET AN UP VOTE ABD LIKE IT!!!

Yeah if you miss the target you adjust your aim.

It depends on what you are practicing. If it involves things out of your control, for instance poker, you definitely shouldn't adjust after every result. In the poker case that leads to not playing well just because you lost one time.

Even in less random things you have to be absolutely sure you found the problem before adjusting.

It's terrible, wrong, and out of context. Einstein was talking about quantum mechanics not mental health. He really didn't like that at the quantum level results are random but follow a very spefic probability curve.

He thought quantum mechanics would be able to achive classical physics like results. Where the only uncertainty was because of measurement error.

quantum uncertainty is the most experimentaly proven theory in physics. So even in the context Einstein made the statement he was wrong.

"There is no substantive evidence that Einstein wrote or spoke the statement above. It is listed within a section called “Misattributed to Einstein” in the comprehensive reference “The Ultimate Quotable Einstein” from Princeton University Press."

So No. I also was always very irritated by this quote, because from a scientific point of view this is rather incorrect, as (like you said) experiments need to be repeated, to verify the results.
