I definitely think in a professional setting it is most important to work smart. A lot of people can work hard, but time is the one thing that we just can't ever get back. In order to go ahead and be the most efficient and utilize our time wisely, you do have to learn from your mistakes and be able to go ahead and create a system that is going to yield the most return. And for that, it's always learning from your mistakes, sharpening the tools that you've already had to become better the next day.
