i experienced CFI'ing for about a year and a half
i only made 4000 dollars and a met 5 CFI's most of them who stab you behind your back and take students, and i met several bosses who would sell their own mother to the nazi's if it protects their asses, and those same bosses, none of them who had their CFI certificate, would constantly be trying to tell you when to fly when it clearly wasnt going to be a learning experience for the student.

i dont feel sorry for those that who missed that experience
