How many of you are Real Estate agents?

I'm asking as I'm curious about doing it but I don't know if I can as I don't want to disturb a potential client/buyer with tics and also I've been trying to look online but I can't find any REAs with Tourette, so am here this is my last anchor.

Also if you're one and have vocal tics how does it affect your work life? Tysm for reading.
