The ability to think strategically is not only intrinsic but also situational.

Even if you have the intrinsic ability to think strategically, you still need space to do so.

If you're starting off in a tactical frame, then you cannot create a strategic argument within it.

The realities of day-to-day execution (e.g. mundane details will take up every square inch of space you give them) tend to conspire to impose a tactical frame on an analysis.
