How do I stop from over sharing/being too deep to new coworkers. - eviltoast

I know I can over share. I know I say things way too “deep” for neutrotypicals. I know how I take small talk into big talk with just one sentence. What are ways that you keep yourself aware in conversation to just be casual. I imagine something small to fidget with that isn’t obvious and I can use to keep me centered on being not so outright. Obviously I don’t like wearing anything but maybe something like a normal but moving or spinning finger ring would help, I can always take it off.

Is this something you guys experience, maybe recognize now, or have realized this behavior and have some mechanism to stay “normal”?
