Sometimes. This is more true when I'm in a new situation that is outside of my comfort zone, like when starting a new job. I like to feel people out and get a general idea of what is "the way we do things around here" and try to avoid stepping on toes. At some point when I get tired of stressing, a switch flips and my attitude just changes. At that point I just tell myself that "it is what it is and people will have to accept that this is how I'm doing it." This hasn't ever backfired on me, and usually leaves me feeling like I was too cautious to begin with.
