I am great believer in practice and deliberate practice especially. Interestingly very few people practice the work they are about to perform. They do the same work over and over and over, and when it comes time to do different work, they haven’t practiced that, so they become trapped doing work they’ve only practiced. Wouldn’t life be better if you could take any job you wanted, at any time, simply because you spent some of your own time practicing for the job you don’t yet have. Generally we call this “school” (or some other notional name) but then school comes to an end, and the majority of people stop practicing for work they are not yet doing.
