My biggest weakness is patience, wanting to see things happen too quickly or get changes in place right away. Not having the patience to let things develop.
— Paul Gleason
That ability to take in your surroundings and sort out the important stuff, to be aware, to be vigilant. Then take all that information, put it together, and see if it makes sense to you.
Confidence, knowing for certain that the person making the call has your safety foremost in their mind. And knowing that the job you are about to take on is the right thing to do, that it makes sense.
