Is it cool I’ve finished my writing my book in 17 hours and my title page in 2 minutes?

The reason I was so quick is that I already had a thousand pages of prewritten cut and paste paragraphs in my folder and a pre-made title page template that took me less than 2 hours to make, I just had to change the wording to match my new book title which took less than 2 minutes to do. And also cut and paste the paragraphs to make a 370 page book.
