In modern mythology there is the 10k hours benchmark for reaching excellence in any domain.
Some people rephrase it as 10k repetitions.
But is not true.
There are 10k Iterations.
On iterations you observe the numbers, you take corrective measures, you repeat. Iterations allows you to hunt for errors and improve the execution.
Repetitions have almost zero incremental educational value.
Do iterations. Improve at each step.
