Limited Times

You had limited time to research. You had limited time to write your thesis.

You’ll have limited time after submission to get ready for your viva. You’ll have limited time to take advantage of support from others and limited time to do the prep work you need to do.

At the viva you’ll have limited time to share your contribution and demonstrate your capability.

Another way to look at all this is “enough”.

For the work you needed to do you had enough time to get it done and enough time to write a thesis that was good. You have enough time to prepare and enough time to get help. At your viva you’ll have enough time to think carefully and enough time to respond to the discussion as it happens.

Time is limited at all stages of a PhD but there’s enough to succeed.
