 == Conclusion
 
-- Lazy is good
-- Lazier is better
-- Lazy with bytecode enhancement is best
-- Sequential queries avoid cartesian blowup
-- The 1st-level cache is your friend
-- Use DTO projections everywhere all the time
+[%step]
+* Use a DTO projection if you can.
+* If not:
+[%step]
+** Check your ``@OneToOne``s.  Use `@LazyToOne` and bytecode enhancement if necessary.
+** Don't `LEFT JOIN FETCH` more than one collection at once.  Use sequential queries instead.
+** The 1st-level cache is your friend.  Use it.
