Professional Degrees and Business
Many professional degrees and programs that offer degrees or certificates, such as law, medicine, banking, and education, etc., do not necessarily prepare their students to run the kind of business the students are training to work in.
Law schools prepare students to be lawyers but not necessarily to run a law firm. Medical school prepares students to be doctors but not many of them offer courses on the operations of a medical practice or office. Banking programs train students to work in banks but are not likely to offer courses in how to start a bank. Education programs train their students to be teachers, administrators, and to work in curriculum development but usually do not teach their students how to start a school or how to operate a school as a for profit organization.
Regardless of whether your business is one you went to school to be a part of or one that has nothing to do with your education or professional training, make sure to run your business like a business.
