An interesting perspective, sir.

I'm definitely, annoyingly, frustratingly, a 'forest' type of person.
(i.e. I'm lazy)

Using this analogy, there are no forests. They don't exist. Only lots of trees.
A forest is a concept.

As I get older, I realize the importance of only looking at the trees - to get things done, and to make the best job you can of something.
(but it is a bloody hard habit to break after decades)

Seeing the forest does have it's advantages - but I would say, on balance, in a day to day time scale - looking at the trees wins hands down.
