I think that the greatest action we can take to improve both our world and ourselves is to cultivate gratitude and appreciation of others. No matter how great or small an individuals contribution, they would be magnified in a post-apocalyptic scenario - even a brief smile could raise one above desperate lonliness, if only for a moment. The most attractive quality in another human being is thoughtfulness. The most frustrating character is thoughtlessness. Many have allowed causal business/social mannerisms to deteriorate into rude and offensive behavior with complete disregard of the receptions interpretation, which includes, but are not limited to, language barriers and cultural misunderstanding. Has playful banter at workplaces fallen into insult and lawsuits? Have we blurred the lines between self-promotion and selfishness at the expenses of others? I suggest that we recall the concept of "scruples", meaning "to hesitate"; while we value quick decisions and action, instead pause before you blurt out your gut instinct and be respectfully aware of how your words and actions affects others. A carefully constructed argument speaks volume, while offending few or none. Greetings from Canada.
