They both go hand in hand. knowledge feeds itself wherever it comes from, to form the person as a whole. To just be book smart would leave you with no common sense with which to interact with others. Then again we see all to often what happens when people have no education. You will be lucky to get anywhere. Education is books & life experience.  Also people do like to see proof of an education.    PS. I needed to re-sit my maths & English O levels due to thinking i could get by without an education (at 43)
