Sitting and Staring

Can one individual really measure upon how fair their lives have been? Can one stare up into nothingness and wonder to himself did I make a difference? Is it the right of someone else to judge me or is it my right to differentiate my doings from right and wrong? Is it integrity when you tell someone how much you love them and care for them or do actions speak louder than words? And if actions really do speak louder than words what must I do?
