What do I hate about my PhD? The time it takes, the rigour I need to apply, having to learn methodological techniques in too short a time, having to juggle life and study, having to balance deep thinking with surface living, living with the uncertainty principle (when you're researching something that is required to be novel, it's difficult to hold onto the sometimes elusive ideas that propel you towards your goal), the need to be constantly organised, to account for your progress, the drive to present, write, share your findings, sometimes in too short a time. But, on the plus side, these are just things I've grown to understand are part of the everyday journey of the PhD, and part of what makes the highs 'high' and the view from the 'peaks' so interesting, so that's okay. Besides, they do make you stronger... or else... you quit, I guess. *wry grin*
