This quote by Charles Dickens speaks with the concept that we are often our own worst enemies. We produce our own limitations and obstacles in life, and then we are forced to deal with the repercussions of our own actions. It recommends that we are the ones who produce our own suffering and misery, and that we are the ones who need to bear the burden of our own errors. It implies that we have the power to make our own choices and that we are accountable for the outcomes of those options. It is a reminder that we must bear in mind our decisions which we ought to aim to choose that will cause favorable outcomes. Ultimately, this quote motivates us to take duty for our own lives and to make decisions that will cause a better future.
"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"
