This world is like a hotel. If a guest sits in his room and waits politely, everything he needs will be brought to him by the hired help. But if a person rushes to the kitchen to take his food, he will have to attend to himself. Similarly, a person who has bitochon will be given his needs. But one who puts excessive efforts into pursuing his livelihood will find that he is forced to do so. ~ R’ Yosef Yozel Hurwitz zt”l, the Alter of Novardok
To be clear, this is not to say that one does not have to do his or her hishtadlus. I think the Alter is specifically speaking of “excessive efforts,” as stated.
