Corporate Cornerstone: Volume One. The Corporate Cornerstone volumes are designed as a brief collection of Marketing and Business essays for the successful business professional looking to further their knowledge. The volumes will be released regularly with fresh and informative topics. This book differs from average business non-fiction publications, as I wrote it to be a summarised, easy-to-read guide which can be easily absorbed by all readers: from the student seeking an alternative resource, to the corporate professional looking to further their knowledge. I hope you get as much out of reading this as I did writing it.
