Smokey will always be making noise. That's hard. I get that. But, *you* are the only one who has control over your focus. You can't blame that on him. If you are tempted to give him that power, then it's time to get to a meeting. He isn't doing anything unusual or unexpected. It is your degree of focus on him that is causing you problems.
How about some mantras?
"That is just noise." "I choose where to put my attention." "I choose to focus on my work right now."
