Quotation Du Jour

I coach impromptu speaking for my college's forensics (speech and debate) team.

As a result, I search for quotations almost every day and frequently come across some that really hit a home run with me. Here is today's discovery, which I found at my favorite quotation web site, QuotationsPage.com:

All is in the hands of man. Therefore wash them often.
Stanislaw J. Lec (1909 - 1966), "Unkempt Thoughts"
