Went to college at age 45. Got my BBA and sent out 200 resumes to companies: No offers of employment. So I went back to doing firing range management, marksmanship training and EOD stuff in the middle east.
Some good jobs did come my way after my MBA. Still do some consultating, mostly in the middle east. Most middle east companies prefer consultants with advanced degrees.
Nope, ain't any smarter than I was before college. But it sure helped the bottom line.
