Do you use the new HTML5 structural elements like header, aside, article, and footer? If so, do you do use them because of the added semantics they carry?
How much time do you put in to understanding the perspective of others? Do you judge anything that differs from your own personal taste as poor quality?
Do you take responsibility for your actions? All of them? Are you sure? How consistent are you with the things you believe and the things you do? They’re harder questions to answer than you might think. We’re all pretty good at finding ways to avoid responsibility when we want to. The thing is taking responsibility is the first step toward getting better and achieving success.
