Have you ever felt fearful or nervous when assuming a higher position of leadership? If so, how did you overcome it?

Two words for you: Maker’s Mark. Drink copious amounts of it before you assume said leadership position and you will do fine.

When I was asked to be Squad Leader, by the Master Sergeant: the girls around me said- "She can't be Squad Leader. In my mind I thought: "Oh Yeah!" ;-) Try not to worry, Corporal. You'll be okay. Think of the fact that you were chosen for a higher position of leadership: with PRIDE! I CERTAINLY AM PROUD OF YOU, Cpl Kevin Henderson!

Yes I have. But, I do my best to overcome it because someone higher trusts/trusted me with those positions and level of responsibility. Best way to overcome (that I have found) is to just go in, express your expectations, be honest and up front, hold everyone (to include yourself) accountable and just do your best.
