'Monumental task'

When Rick Mills was a commander in the U.S. Army, a subordinate once commented that it seemed like Mills rarely made a leadership mistake.

The statement surprised Mills. And he knew it wasn't true, especially in military, where missteps were sometimes unavoidable.

“I told him I had made a lot of decisions I didn't like, but I rectified them,” Mills says. “If you feel like a decision you made wasn't the best, you need to own it, address it and correct it. And the more difficult the decision, the more you have to own those and be accountable.”
