THE advice we get to become experts is to PRACTISE a lottt.
But, what does it really mean to practise? Is there any correct process of practice? Daily quota? Rest? Following materials of previous experts or tinkering until it works? Is there any field specific advice?
How did YOU do it?
Repeating something 100x builds rote or muscle memory. Doing new things 100x expands one’s horizons. Both are useful. The Beatles learned how to gig in Hamburg. They learned how to record at Abbey Road. And even at their peak they worked with others.
