With most PhDs spanning 3 to 4 years, it is not a decision to take lightly.
For some students, their passion for research and a specific academic discipline is such that a PhD is an obvious choice as part of their career planning, however, for others it is just one possible option, prompting further questions.
Having an insight into what life is like as a post-graduate researcher is a crucial first step. Without any doubt, you will need to love learning, have a hunger for research, and be a self-starter happy to work for long periods independently. Advice from vitae.ac.uk is to be ‘really clear on your motivations for doing a doctorate, and that it [will be] a positive career step.’
