Each of us has an individual preference or taste. Likewise in the work that we do, we will also have our personal favourites. This choices are sometimes ingrained in our DNA or that it could be developed over time with the exposure that we received as we were growing up. And doing what we love feels much different than working on something that we have little to care for. We have more energy, passion and ideas while doing work that we love. We do not mind the extra hours that we have to put in. In short, we do our best work. And that is our responsibility to ourselves, the people around us and the world at large.
