First Few Weeks Full Thickness Tear Repair

Hi guys. I've got surgery coming up for a full thickness tear of the supraspinatus on my right shoulder. Trying to lock down the date.

I've got benefits so I can be off work for post surgery, but I have other things I want to do. I'm supposed to be in a show at the start of September. How much activity is reasonable to expect of myself in the first week or two after surgery?
