I saw your question today.Dec 19. After 3 months Im hoping you have accomplished your goal. To becoming a General Manager, Im afraid there are no short cuts,its about your experience through the years, and the knowledge that you have.
Alot of people get 4 year Degrees, and start this way. Alot of people( like myself,have 18 yrs of life experiences ) I started out as a Shift Manager, and have worked my way up through the years to a District Manager.But I did every job between here and there and was the very best at it. This is important now days. My best advice, is to be a " hands on Manager" these are the people who excel, this is what Companies desire.
