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.

How much effort is excessive? Doesn’t the answer to that question depend on how much you need to support yourself and your family?
