As human beings who wish to be loved and to love in return, we need to focus on the simple things in life, the small successes that help us reach our larger goals. We don't need to walk over everyone to climb the ladder of success, oftentimes that ladder will be reached quicker with less chaos when we use our innate relationship with others to work with them instead of working against them.
So, what's the lesson? Life has its sugar and spice moments, those moments when we are extremely gentle and kind and those moments when we must stand up for ourselves or others (those horrible, unpleasant situations), but for the most part we should fill the majority of circumstances with the "sugar" moments. We will get further in life and eventually, when we get older, there will be much less regret if we learn to love and work with others, instead of always pushing our own agenda.
