I must be nuts

I think I may seriously have a mild case of ADD.
I started a new project yesterday.
I've always wanted to make a cathedral window quilt.
Yesterday I saw one online and suddenly HAD to try the technique. I could think of nothing else.
I couldn't find instructions on how to make the blocks using the traditional, hand-sewn method anywhere online.
I had to resort to a book. Gasp!

According to the book, for a twin sized quilt you need 572 background squares and 1100 colored squares.
I may be making a table runner.
