For me, these conversations really highlighted the importance of doing things in teams and that effective teaching can't be done on your own...well at least in my case. It also hit home the fact that if you've got a question, ask it. I often tell my students there is no silly question and that we are all 'life long learners' yet when it comes to my own learning I don't necessarily apply the same thinking. I find myself not wanting to ask questions in fear that the answer will be so obvious to everyone except myself, therefore making myself look stupid. Dumb eh? It's the same reason my students don't ask questions.
Moving forward, my goal is to ask more questions about my own teaching, and not just to senior teachers but to any of my colleagues. Who knows what gems of magic I might find.
