The PhD is not a sprint or marathon. The closest is maybe the hurdles event: a series of barriers to be cleared. Literature review has to be cleared so you have a good background understanding. The transfer viva has to be vaulted so you can progress to second year. Submission has to be jumped over to get you to the viva.
The viva, the final hurdle. Since you have cleared all of the others to get this far, why would you fall at the last one? Is it really higher or more difficult than everything else you’ve done?
You still have to leap, but you’re good at that. You have to be ready, but you can be ready. You have to be talented – and you have to be talented.
How else have you got this close to the finish line?
