Here is an excerpt from Scientific American:
People with good writing and research skills are rare. People who cross disciplines and read widely are rare. But don’t we need these people for academia to thrive? After all, many times, the greatest innovators are those who bring in fresh eyes and the perspectives of fresh disciplines: they are less likely to be myopic and be constrained by lines of thinking that are area-specific—and more likely to see patterns and connections that are invisible to the insiders.
The single best training and preparation I could have possibly had for writing my dissertation was the exact training and preparation I received in my career as a blogger and a writer. I just hope that others can have that same experience, and that in the future, my path will be the rule rather than the exception.
