Controlling is fun, but there are times where you have to remember there’s someone else receiving the commands you send. It’s not worth opening all stations at the hub airport in peak time just to show people you can. The quality of your services will inevitably go down, and it’s not worth ruining the experience for the sake of your ego. It’s not worth accidentally issuing a Level 3 to the wrong person because you want that promotion to Officer. It’s not worth crashing someone into a mountain because you were watching YouTube while controlling.
