if you have married friends, periodically call them and remind them what you’re looking for – maybe their husband knows someone. have a clear descripotion in your head of what you’re looking for and tell it to people. the person who made my shidduch was from completely different circles than i am, but when she asked what i was looking for, i told her exactly what. she said i know the guy for you. i, of course, didn’t believe her. but, through some strange circumstances, she did know him and described for the first time in about 10 years exactly what i was looking for. you never know who will be your shaliach. do whatever hishtadlus you could do; while at the same time davening from your heart and because you want to get married, and not from a place of burnt out, giving up or depression.
good luck.
my sister hadn’t dated anyone for a year when all of a sudden the right name came up and she married the guy. happens all the time. “yeshuos Hashem k’heref ayin.”
