Im not sure how many bochrim in this generation would make major life decisions to please Gedolim/Klal but…
There was once a (true) story in one of the frum magazines where a Chasan got cold feet the day of his weding. A Gadol (cant remember which) asked in Bais Medrash whoever wants to marry this excellent girl today, will merit long life and a good family. One bochur agreed. On his 50th or so wedding anniversary this “bochur” was asked to what he attributes his old age and beautiful family and he told of the Bracha given to him on the day he agreed to marry his wife (on trust of the Gadol’s opinion and Bracha).
If anyone remembers details, please share. This is pretty much what I remember reading.
