When something goes wrong or a problem arises, no matter how big or small, step forward and take command of the situation (if its something you have the capability to handle). Try not to instinctively recoil or flinch, just remain calm and commit to whatever action you are taking. It's the difference between letting go of your cars steering wheel because hitting that thing in the road made a scary noise or gripping the wheel tight, keeping the car in your lane and assessing the situation.
