In Vera F. Birkenbihls accompanying text  to Heinrich von Kleists »Über die allmähliche Verfertigung der Gedanken beim Reden« (About the gradual fabrication of the thoughts while talking) she makes refferences to the two following books: »The open and the closed mind« by Milton Rokeach, published by Basic Books in New York in 1969 (which is unfortunately out of print) and »Sprache im Denken und Handeln« (Speech in thinking and doing) by S.I. Hayakawa. Among her ca. 30 publications,  I will allud especially to the volume »115 Ideen für ein besseres Leben« (115 ideas for a better life) and the new title: »Birkenbihl-Power-Tag« (Birkenhil-Power-Day).
