Me too. But, oddly, my experience has been that writing generates ideas, and sometimes those ideas don't coincide with narrative chronology. And if I don't deal with them when they're fresh, I lose them. So, often, as I'm going along, I need to flesh out something that might could maybe kind of perhaps fit in later. So I divert to write whatever scene(s) that happens to be, at least in very rough form. Sometimes it gets jettisoned later, but more often it provides a target to write to, and is fitted appropriately.
But this is most certainly a thread that results in: Whatever gets you through the night, in your writing. There is no Right or Wrong.

I take to a lot of writer who say more or less the same thing, and it works wonderfully for them. I wonder if I never get ideas fro later in the story because I force myself to look back continually? I simply don't let myself look ahead, and I force any idea about later in the story out of my head , should it dare enter.
And we've talked about it before, but I think the best thing that can happen to me is losing an idea. If I can forget something, I'm glad it's gone because if it wasn't worth remembering, it wasn't worth using. That's why I write nothing down.
For whatever reason, looking ahead just doesn't work for me. I can't seem to make the parts fit, can't work toward the ahead part, while making the story flow.
I've often had to write detailed outlines for editors before writing something. but once I get a contract, I never follow the outline. I ignore it completely, and writing what I want to write, and write it my way. Editors don't seem to mind. The outline is really just an excuse to offer a contract, not something I really have to write. For me, this is a Good Thing.
