Thank you,

That link contains some important views I agree with to some extent. The author also mentions many real life examples...
The slightly different "twist" in my own ambition is that - yes - I would be honored to be a "general" - a "Steve Jobs" - who can see the interconnectedness between all fields
(funny, my friends always complain about how I try to put together things that are totally unrelated... like dance choreographies for Heavy Metal Music :P ), but I would also enjoy being the one who creates the final design of the iPod, designs and checks its safety and ergonomics features, programmes the hardware necessary to run it, films and projects its advertisement, etc.
In few words: I would like to be more "hands-on" in what I do (something that from what I have seen, managers or directors rarely do) - and not necessarily within the same company or industry.
I would like to be a passenger flight pilot for 6 months, a road cleaner for another 6 months, and a research scientist for another 6 months...
Given our standards of professional and health regulation, this would be crazy if not extremely dangerous to society.
