Organization charts and fancy titles count for next to nothing. Never let your ego get so close to your position that when you position goes, your ego goes with it. Fit no stereotypes. Don't chase the latest management fads. The situation dictates which approach best accomplishes the team's mission.
Perpetual optimism is a force multiplier.
When picking people look for intelligence,judgement, and most critically, a capacity to anticipate, to see around corners. Great leaders are almost always great simplifiers who can cut through argument, debate and doubt, to offer a solution everyone can understand. Once the information is in the range of 40 to 70, go with your gut. The commander in the field is always right and the rear echelon is wrong, unless proved otherwise. Have fun in your command.
