One of my favourite meeting types is the one I just had this morning: in which you know you're competent enough to be in the room at all, AND you know you have room to grow, in terms of both organizational knowledge and personal professional development. It's not like "imposter syndrome"; it's this delicious sense of "I have work to do on myself and now I know how to do it better."
I haven't been properly mentored in years, but BOY HOWDY, do I love it.
