That's a cliche which does not apply to all great people regardless of profession. Sounds all righteous and cool but you are making me laugh, not personally at you, but at that sentiment. I have seen people in various professions who do not 'live and breath' their respective professions but they are so talented and can switch that on and off. The problem with a team though and you have multiple guys striving towards one goal... that is something you cannot not switch on an off because it requires continuity
