I'm no psychic, but I'll bet "don't be a tool bag" will soon be offered up as advice.
Other good tips; try to listen more than you talk. But don't be afraid to ask questions that you NEED answers to. Keep your rig clean. Always offer patients a blanket. Don't ever think you're too cool to hold a scared patient's hand. Keep 5 bucks in your pocket for when you need a snack. Never pass up an opportunity to pee.
You never stop learning soo just remember that. And like said earlier never pass up an opportunity to pee, that's a big one
