How do I deal with resenting my invisible behind-the-scenes work?

You can organize a mountain of footage flawlessly, and you resent that the better you do it, the more invisible it becomes. That resentment makes sense. There is a real sting in doing the groundwork that everything else depends on and having it noticed only when it is missing. Good organizing disappears, and being disappeared does not feel fair. Here is what is worth holding: invisible is not the same as unimportant. It is often the opposite. Your work is invisible because it is so solid that the people downstream never hit a snag, never lose a file, never feel the chaos you quietly prevented. That is not a lack of value. It is value working perfectly. Since the recognition will not come reliably from outside, take it from the truth. You could let the resentment sour into sloppiness and watch everyone suddenly notice what you did, or you can own the quiet pride of being the reason it all runs. Choose the pride. And where you can, make your contribution visible in small ways, so the credit catches up to the work.
