I constantly make sure that whatever I am doing I put myself into the work. By doing this I feel you put out better quality work. This also could be another way to describe having passion for what you do. The work ethic and belief that you have will depend a lot upon yourself. Then also it will depend how much and how hard you are willing to go farther than the other person.
So start putting yourself into your work and then you will start to see changes in you and the world around you.
