"Cull Mercilessly," as Polyglot suggests.
I like the word "winnow," defined by the Free Dictionary as "separating the wheat from the chaff," and more importantly, "to examine closely in order to separate the good from the bad..."
I visualize the process that I use to produce a satisfying print as one of winnowing. Since switching to a large format camera I certainly winnow the number of exposures I make down to ones that I think will make good photographs. Most are winnowed out after I see a proof print of the negative. The rest I begin to work on as enlargements, sometimes stopping when I see that my vision at the time of exposure, for whatever reason, will not or can not be realized. Sometimes I see different possibilities for a print and am led in a new direction. Occasionally my original vision is realized.
In "Art and Fear," Orland and Bayles suggest that the purpose of 90% of our work is to allow the 10% to soar. That sums up my photographic philosophy and work flow pretty well.
