In the PhD (and beyond), we sometimes face a difficult situation, and we have to take a hard decision: do I leave my PhD? do I take an unrelated job to earn more money while I try to finish the PhD? do I seek a new supervisor that better supports me? do I accept the change of direction that my supervisor is suggesting? In this two-part post series, I will not give the answer to those hard questions, but rather provide a decision process that can help us find the option that is right for us, in our particular circumstances.
