It states (Avos 4:12), בתורה ועסוק בעסק ממעט הוי, "Work less and study Torah." You can work less, and Hashem will support you.
It states in this week's parashah (22:35) that the malach said to Bilaam, האנשים עם לך, "Go with the men," permitting him to go with שרי בלק, the officers of Balak. But he warned him that he won't be able to say anything Hashem doesn't allow. Why did the malach permit Bilaam to go? Rashi writes, לילך רוצה שאדם בדרך אותו מוליכין בה, "In the way that a person desires to go, he is led."
Tzaddikim say that it is the same regarding parnassah. Many people work many hours to earn a living, thinking they have no choice. But there is another way. He can choose to work less and to spend this extra time in avodas Hashem, and Hashem will support him. He will receive brachah in his parnassah, in the fewer work hours he puts in. Hashem will lead him and grant him success on the path he chooses. It is on the path a person desires to go that he is led.
The Divrei Shmuel zt'l says that when the Or HaChaim HaKadosh was Rav in Morocco, he advised his community not to work six days a week. It is sufficient to work the first three days of the week, Sunday, Monday, and Tuesday. At the end of the week, on Wednesday, Thursday, and Friday, they should devote themselves to Torah. The Or HaChaim guaranteed them that they won't lose money because of this.
They followed his counsel, and they were successful. They didn’t lose money because of it. Obviously, when one devotes three days a week to study Torah, he will become a better person, enriched with yiras Shamayim and good middos, and that's what happened to this community in Morocco.
A few years later, the Or HaChaim moved to Eretz Yisrael, and the people in Morocco gradually returned to their old customs of working six days a week. They thought that this would increase their income. But they soon admitted that they earned the same amount as when they spent three days a week studying Torah.
