I don’t believe in doing things just because they’re “good for shidduchim.” Conversely, I don’t believe in not doing things because they’re “bad for shidduchim.”
Let’s face it: if you’re the type of person who runs around and around in revolving doors for the sheer joy of it, the Women in Black who find this behavior offensive are not going to be able to help you. Or maybe they will: by setting you up with an equally offensive gentleman – perhaps someone who slides down banisters in his Shabbos suit just because they’re there.
And finally, if you’re doomed (and “doom” has “fate” in its etymology, meaning it’s predestined) to be single forever, it doesn’t matter what you do, so you might as well enjoy yourself.
An early inspiration of mine was Miss Klein. I think she’s still single. I hope she’s thoroughly happy.
