What's a ...well certified mechanic...?? In which field? Vehicles or other machinery?

The main problem with schooling for a degree, for example, ones' learned information becomes outdated after the 2nd year of schooling, therefore, as another example, after a 4 year learning curve, one may well have seemingly wasted one's time as one may well be only half edumacated in one's endeavor.
With such degrees, applying to lesser positions, one is usually seen as OVERqualified or OVERedumacated.
Such qualities USED TO BE FAVORED.
Good Luck Mate!!
