Yup, generally speaking professional environments and thug tendencies don't mix well. That's because thug tendencies put people on edge instead of letting them concentrate on the work.
I don't bring much of my personality into my relationships with clients either. It's one thing to expose the human side a bit when starting conversations. It's another thing to fly blindly down the aggressive and self-aggrandizing tunnel of "Keepin It 100 For All My Real Software Ninjas".
