“PhD students and personal business persons, never stop thinking about their own works at a workplace and at home, everywhere!” A common point between two totally different persons is that their success are depending on their own efforts, so they cannot stop thinking about their works every time and every place even if they stay with their family at home. It is pretty tough to extract the works at home like below a cartoon. How about your life as a PhD student now?
