Being Hard On Yourself
Any candidate could have done more or could have done things differently during their PhD.
There always other options. There are always missed opportunities. And there is always the benefit of knowing now what you didn’t know then.
Reflecting a little about possibilities could be useful, but will it help to be hard on yourself? Will it help you get ready for your viva by stressing about what you could or would or should have done? Will it help to put that extra pressure on yourself?
There is a big difference between reflecting on the journey and thinking about what you “should” have done. Mark the line and don’t cross it. Don’t be hard on the person you were when you did the work. Don’t be hard on yourself now as you get ready for your viva.
