This is in-line with most of the what I've heard from friends scattered around AD.
I'm heading to Tyndall to start UABMT this November. ABM was the only job I competed for, and I feel lucky for having received a slot. The best piece of advice I ever got was from a Colonel who came to visit our detachment: "No matter what job you end up doing, be the best at it."
I know there's really nothing I can do about the reputation of LT controllers being worthless. As a Lt on my way into that AFSC, however, I want to do everything I can to at least be the best worthless LT controller.
