Then all of a sudden, the little troubles we bicker about and worry about fade away.
You wouldn't stress about that one exam coming up, or that one time someone was rude to you.
You would probably spend time wth your family, and get off that darn phone.
You would probably go walk in nature, taking all the complexity of life in.
The truth is, we all walk on the very tight line between life and death. Every moment is not guaranteed-- it is not certain that you will wake up tomorrow. Even now, the whole world could spontaneously erupt in nuclear war, and everything would end.
Sometimes, we forget how fragile our existence is, and toss it around without care. Treasure every moment, because you don't know how many there might be left. Live like you are dying, because you are.
