I love the process. The need to be on your game to capture a prefect moment, to interact with clients, to manage their expectations and deliver a product which underscores the value of professional photography.
With commercial shoots the key is to set expectations upfront. A run sheet, what the client can do to get the most from the day, what to expect from me on-site, where I will place equipment, etc. when the client feels informed they can relax and let the session unfold. For events it is very important to take charge, to be personable and (gently) guide people to capture the best moments. Also, to contrast tha, it's important to also be invisible when required.
I typically receive great feedback from client, but was formally acknowledged by this year's Casey Relay for cancer for doing a great job at their event.
I'm also a jazz musician and play regularly around town.
