A person who drives himself ambitiously to earn his livelihood is like the passenger who impatiently pushes the wall of the train in a vain attempt to make it move faster.
All of a person’s income is determined on Rosh Hashana, so why should he wear himself to the bone struggling till he makes himself ridiculous?
What has been decreed for him will come to him, and even if he turns the world over, he will not receive a penny more. ~ R’ Yosef Yozel Hurwitz zt”l
