Photography

So I'm going to Paris in a few weeks, and I will be bringing my new 70-200mm f4 for the trip.

However, i have this thought in my head that I don't really know what to photograph. I usually take pictures of people and situations with people in them, as those are memories I want to hang on to.

When I see a lot of street photographers on YouTube etc, I feel like they take some well framed and pretty, but also irrelevant images. Would they ever go back to an image of a busdriver they snapped at an intersection?

I'm not putting those people down, but I personally have a hard time seeing the real value in that. I guess that simply making a nice shot is a great feeling. And a really nice shot might o ly happen once every 1000 images.

But what makes a nice image to you? Can the image stand alone? Or does it have to be part of a series with a certain theme to it?

I'm looking for some fresh perspectives on street photography that will get me excited for my trip :)
