First settle what is important before certain emergencies. Be careful not to let your work lead you, to let yourself be overwhelmed by what is urgent at the risk of being swallowed up. Try to understand first, then to be understood. Live a life focused on the essentials. Get ahead of emergencies.
It is the serenity at work that saves you stress. So know what to do every hour, every day, every week, every soft, every year. And you in this way, you will have warned emergencies. And even if the unpredictable invites itself into your work, you will not let your guard down, you will stand up.
