I guess one positive (as mentioned by a former manager) is my ability to stay very even keeled. Basically I stay like a rock, very rarely getting worked up about anything. He described me as being like a rock. Always in early, consistent quality output, no drama, and stuff just happens correctly and on time.
It's actually to the point that the one time I blew up and lost my **** at an inspector out in the field that all three of my foreman and crews literally stopped working to look at what was going on, my superintendent hurried over(his thought was 'Uh oh, this is going to be bad') and the kicker was that the inspectors boss called my boss and actually was calling to check in ME. Basically "Is everything alright with X? Nobody has ever heard him raise his voice like that". Didn't care about me yelling at his inspector, but I guess was actually worried about me.
The truth behind it is that I'm rather emotional underneath the facade (I'm not one of those people that can scream and yell and then calm back down in 5 minutes). If I get really mad about something it burns/stews/simmers for days. I don't hold a grudge against people but I don't calm down easy. Plus I don't do shouting angry I do the almost in tears angry (which is not something to be known for in the construction industry).
The list of negatives can be simply described as looking in a mirror.
