I completely disagree with you that it is it necessary for one to get an orientation about a business before it started as far as I am concerned, we all need a form of business orientation in one form or the other for that business to succeed at the we have the experience for the business or we go and learn about the business and that is also some funds of orientation for the business.Well I don't think it is necessary, but u do think that if you have the opportunity to learn from a pro or master in a particular field or area, why not go for it. Added knowledge is always a blessing and now you have learnt from the best.
