There’s a lot of light cast around during the PhD process.
You shine a light on a topic you found, and create more when you write your thesis.
You brighten up your thesis when you prepare for the viva.
Your examiners bring your work into full sun, although hopefully it won’t feel like a harsh glare.
And fingers crossed you won’t have to burn the midnight oil to add a little more light with your corrections.
Every step of the way you illuminate something because you’re making it easier for someone else to see the value of what you’ve found.
Keep on shining.
