The acknowledgements page of a thesis is a lovely opportunity to be thankful.
Thank your supervisors for all they’ve done.
Thank your family and friends by name.
Thank your funders if you have them.
Thank anyone who has really helped.
Looking back at mine, and at others I’ve seen, the acknowledgements page is a time capsule. A little slice of a time when you were someone else. I’ve not stayed in touch with many of the friends who helped me through my PhD. That page reminds me of who I have to be thankful to, and who made a difference.
Say thank you.
