Definitely. I feel like I'm constantly asking myself "Was that the perfect thing to say?" "Was that the perfect way to acknowledge someone as I passed them?" "Is this the perfect thing for me to be doing right now?" ad nauseum, not consciously necessarily, but when I try to get to the bottom of why I'm feeling anxious and stressed, this usually seems to be what I come to.
I'm working on reminding myself that there's no such thing as perfect a lot of the time, that it's ok to do things differently than other people, that I do good even when it's not perfect, etc., but it's hard.
