Furthermore, the gemara in Taanis 24 quotes the following story but I’m not sure where the main gemara is. Anyway:
Rav Yehuda, during a draught, would simply take off his shoe and rain would fall; but, we (Rabbah’s generation) scream all day to Hashem and no rain falls. And it’s not because learning was better in Rav Yehuda’s generation. It’s much stronger now. Rather, why was Rav Yehuda answered but we’re not? Because they were moser nefesh and we’re not.
