Assuming we still don't have any business relationship before we take part in our ideal jobs or fields. For instances, you decide to apply for a salesman in finance field but you don't have any contacts which can bring benefits to you.
What must you do to build a potential business relationship quickly from zero? ( i understand that we shouldn't just care about benefits or advantages when we make a relationship but as a businessman, i suppose that advantages is the most important thing we should focus on if we decide to make a business relationship )
Thank you !
