Decide Whether to Pursue a PhD or Leave Academia After a Master's Degree

You are considering a PhD and you are not sure whether it is the right path or whether you are staying in the familiar environment of education. This gives you an honest assessment of what doctoral study actually delivers and what it costs, three questions that distinguish a genuine candidate from someone who is deferring a decision, and the one field where it is clearly worth it and the one where it rarely adds value. Good for Master's students making this decision without the institutional pressure to stay.
