I love the idea of Malcolm Gladwell’s 10,000 hours. Basically, if you want to “master” anything, you have to put in the work and deliberately practice for roughly 10,000 hours.
One way to accelerate that timeline without experiencing all of the setbacks is by reading where others have tried and failed, what they learned, what their best practices are, things to keep in mind, etc. That’s why reading is so important. Even though it’s not the same as doing (and you typically don’t retain as much reading about something versus doing it), you can still add to your skill set by learning as much through books when you are unable to learn by doing.
Whenever you have the means to do something though (whether that is not having time, money, or energy constraints), then do it. Make a plan and intentionally follow through with that plan. There is no substitute for doing. You can have a good understanding of a subject by reading about it, but if you never do it (and preferably teach it too), then you will never truly master it.
