Your definition of 'practicing' is different from the publication's - the publication specifically looks only at
deliberate practice:
>This view holds that expert performance largely reflects accumulated amount of deliberate practice, which Ericsson et al. defined as engagement in structured activities created specifically to improve performance in a domain.
As an entrepreneur or programmer, I think that it's very hard to do deliberate practice - there are few structured activities you can do to improve your skills, as both fields, even in their more basic tasks, incorporate various skills and approaches.
For example, you wouldn't say 'today I practice for-loops' and then do nothing but write for-loops all day. You can say 'today I write a program that uses while loops instead of for-loops', but I think that wouldn't count as deliberate practice anymore - the structure of the task changes with the focus and task of your program (you'd also have to do more like de-bugging, tests etc.)
As a tennis player, however, you can say 'today I practice serves' and then do nothing but serve balls all day, that's a structured task that doesn't change. Apparently it just doesn't help that much.
