I heard some good ones are not being hung up on yichus,not needing someone with the exact same ideas as you to the letter.
Also, not letting a prospective match go because they have one of the following: Divorced parents, a 3rd cousin who went off the derech 20 years ago, saw a therapist, had the flu, saw a tv once,uses a different type of tablecloth on shabbous.
all excellent segulos and excellent practical suggestions!
