This quote by Abraham Cahan speaks with the short lived nature of life and how rapidly it passes us by. It recommends that life is much shorter than we think it will be, which we ought to take advantage of the time we have. It is a suggestion to live life to the fullest and to not take our time here for approved. It is a call to action to make the most of our lives and to not waste time on things that don't matter. It is a pointer to focus on the things that bring us joy and to maximize our time here. Life is precious and it is important to make the most of it. We need to make every effort to make the most of our time here and to take advantage of the opportunities that come our way. Life is short and it is important to make the most of it.
"Life is life - whether in a cat, or dog or man. There is no difference there between a cat or a man. The idea of difference is a human conception for man's own advantage"
