The joy of writing was so great that it often happened quickly and easily. Sometimes ideas and texts came to her when she least expected them. "Like, for example, Master Detective Blomkvist, he came to me in our rowboat in Furusund. And it goes so fast that I almost feel embarrassed when I hear how many others work hard on their books. I have a strange feeling that the book is already finished when I start writing; I'm just there to transcribe."

Astrid's enormous work capacity is well-known. To manage demanding publishing work while also pursuing her own writing is undoubtedly admirable. In the mornings and early afternoons, she writes or transcribes her own books at home in bed. After a quick lunch and a brisk walk to the office on Tegnérgatan, she began her work as a children's book editor in the afternoons.

For several years, Astrid was solely responsible for children's book publishing at the publishing house, while also managing her own international sales. However, in 1952, she received assistance from Marianne Eriksson, who was the editorial secretary, and Kerstin Kvint, who started as an office assistant and eventually became responsible for international sales at the publishing house.
