--- Reputed to have been said by a meditation teacher. Via John Givot, while chatting at the conclusion of a 10-day sit on 12 March 2011 about the importance of admitting one's weakness to oneself. A web search on 14 March 2011 didn't yield any attribution; in fact, many of the results for the string "giving up is half the battle" were people saying "not giving up is half the battle" :-)
