Advice to someone who wrote about the situation of his parnassah, who did not wish to elaborate on the hardships that he went through.
The Rebbe replied:
This is not necessary. Just consult with good friends who are knowledgeable in this field to analyze why you are not being successful, although others in the same situation were successful, in order to correct this situation in the future.
=== Igros Kodesh V34, P184
Many times, in business decisions, the Rebbe would answer, “Ke’atzas yedidim mevinim – consult friends who are also experts in the field.” This is based on a passuk in Mishlei [11,14]: Uteshua b’rov yoetz – Salvation [comes] with much counsel.
The reason to seek advice from friends is that they know your character well, and they care enough to give you the right advice.
