On man find we see:

       -quit  Exit  immediately.   No  child  processes will be left running,
but no more paths specified on the command
              line will be processed.  For example, find /tmp/foo /tmp/bar
-print -quit will print only  /tmp/foo.   Any
              command lines which have been built up with -execdir ... {} +
will be invoked before find exits.  The exit
              status may or may not be zero, depending on whether an error has
already occurred.

Also add an example:

Indeed this can be used to quit immediately if any -exec has an error:

$ find \( -exec perl -e if {} \; -o -quit \)
syntax error at -e line 1, at EOF
Execution of -e aborted due to compilation errors.

Instead of the error repeating 1000 times.
(The error message came from perl.)
