I also have that issue, so I try and focus on not going too far down the rabbit hole if it’s not relevant.
If I’m speaking to my boss I’ll say:
“This happens because of that, I’m gonna fix that”
As opposed to:
“What’s happening is X does Y, then Z occurs. That’s because of the A and B not being quite right, because B is blah blah blah. I thought about trying option 1, but that doesn’t work because blah, option 2 doesn’t work either because blah, but option 3 works because of blah blah blah.”
If they don’t need that info, then you don’t need to share it.
