I have always been “that guy”.
At my old company, the years of abuse brought with it possibly more sarcasm than was warranted. A Co worker, as I left, told me he thought if I could tone that down a bit, my skills would take me places I did not expect. Damn, was he right.

Yeah, a little civility can go a long way of you have any talent at all. It has taken so to the top of the pile with no discernible skills.
Courtesy is something I have been attempting to add to my skill set for some time now. Not at successful as I like, but helps.
That’s good news! :-)
