Permission is not the same thing as responsibility. If it’s not your job to fix the leak or to improve the agenda, it could be. You probably have permission to do it from your peers already, but check with them if you’re stressed about it. Then take the permission to make something better.
We need to take responsibility when something we own doesn’t work. We also need to take permission to own things nobody presently is, things that need doing.

Well said. I might add something I’ve heard: “It’s easier to ask forgiveness than to get permission.”
When you see something that needs doing, get in and do it. Of course, I seem to be around a lot of people who don’t see what needs fixing. They are complacent with what is.
