Good morning,
In case I have a terminal cancer that will lead to death, the first thing to do is to submit myself to God entrust my life. I will be doing charity work and stay happy. Accepting the truth will lighten my burden because I know people will not die because of what their sickness but they die because it is the end of their life span in this world. Nobody will stay alive in the world. We are ordained to die and rise again. A lot of people around died in an accident or death in the morning when they are just sipping their coffee. So if I have a situation like that, I have to accept it and I will make it sure that I will be leaving with good memories to remember from the people around me. I am willing to leave on what I have in this world.

Today even though I have no terminal cancer, I am now living my life thinking what my whole day brings me, sleep at night and if God let me wake in the following morning, that would be a great consolation.
Live your life of what today brings you and no need to worry for tomorrow
It literally means you have acceptance and contentment.

Thank you @anomadsoul
