If you don't want all that junk that goes along with a find output from /, then use the 2> /dev/null.
This will send all erroneous messages that would normally come from stderr to stdout and send them to /dev/null so your screen will only show you the result you are seeking or nothing if the search had no result.
find / -name myfile 2> /dev/null
My brain is your brain....
