If you google ‘management quotations’ you’ll be inundated with hundreds of responses. The four sites listed below are those that I found most useful.
Remember to use a range of search terms when looking for management quotations. In addition to ‘managers’/‘management’ try ‘leaders’/‘leadership’, ‘motivation’, ‘change management’, ‘decision making’, ‘business planning’, etc.
