I have a friend who likes to say, "you have to know where to go, know what to do when you get there, and know what to do when you get home." He's obviously a landscape photographer, but I think his simple mantra sums things up pretty well.
Well, darn. I spend most of my time being lost....
All of this is, imho, of course ... and just for the sake of a fun discussion....
I like to categorize photographers by where they are on the Hunter <--> Gatherer spectrum.
Hunters like to prepare for a shoot. Like your friend, they like to know where they are going, and what they are going to do when they get there. They like to pre-visualize what the image will look like, sometimes before they even leave the house. They know what time sunrise/moonrise is (if they aren't studio shooters), and where the sun or moon will rise. If they have an iPad they have an iPad for that.
They will set up where they need to be, before they need to be there. They will be ready when the scene unfolds and opens up.
Gatherers look outside in the morning, notice the light is good and start throwing things into the camera bag to get out while the light is still good. If they are really organized they looked at the weather report the night before, and prepacked most of their camera bag. Except for the batteries they put into the charger that night. In the morning they will normally remember to pull the batteries out of the charger. (I'll put my car keys next to the charger to make sure I don't go anywhere without a spare set

).
Gatherers will typically wander more or less at random, or with a barely defined notion of where they want to go.
Gatherers rely on "seeing" things in front of them to capture. To see how a scene unfolds, while they are there and present. Sometimes they will even recognize that where they are will
become a great photo in an hour. Some will even hang out there until they get the photograph. Some will try and come back.
Gatherers are very good at seeing a great photo in unusual circumstances and locations. They see photos everywhere. But they couldn't tell you the phase of the moon if their life depended on it. But if something interesting is happening, they will see it. If they happen to be there.
Hunters will often trip over a great opportunity, without ever seeing it. They are focussed on the image they are hunting, and often miss anything else. If they are photographing the fall colour in a forest, they won't even see the sasquatch having lunch behind them.
Most photographers have elements of both, and the best photographers have the best of both.
I tend to be a gatherer outside, and a hunter in my studio.
