I think there's too much focus in general (not necessarily on this forum) in being 'this' kind of person or 'that' kind of person.
In most areas of life, including Go, you need to be able to focus on things at different levels. For example in Go, there are your local tactics and your overall strategy (yes, a huge oversimplification of the game
).
You might have a really powerful local tactical play, but if it doesn't support the overall strategy, it's useless. Likewise, to plan your strategy properly, you need to grasp details about the strengths and weaknesses of groups and the various tactics available to choose from.
What I'm basically saying is that tactics inform strategy and strategy informs tactics. The two are inseparable, but strategy always trumps tactics. I think this is one of the important things that Go can teach people.
<rant>From my own experience, it's an understanding that is severely lacking in the workforce. I meet people all the time who say 'I'm a details person' or 'I'm a big picture person, I don't do detail' - in other words... 'I have no idea what's really going on'. What's more, people love to apply these random labels to other people.</rant>
I've noticed that the most effective and successful people tend to do both. Just like a good Go player. You don't need to know every detail to the nth degree, but I think you do need to know enough to understand how it affects what you're doing.
Regarding noticing punctuation and other things, it's a trade-off depending on how much time you have and how important it is. There's a things called the ETTO principle (efficiency thoroughness trade off) which is partly about that. Once again this also applies to Go.
