WTP – I think the mesirus nefesh factor is no longer a part of it, which is why that this has not solved the shidduch cirsis.
I heard this beferush from Rav Meir Brenner. He said when he was young it was next to impossible to find the tziun – it was in the middle of the forest with no path and just an arrow carved into a tree or a rock every now and then. He said a person could maybe spend a couple of days in the area looking for it and still not find it. Because it was such a challenge, for the people who were zoche to find it they saw many more miracles whereas nowadays you don’t see every a miracle story for everyone who goes because it’s so much more accessible.
