I've got plenty of technical, maintenance knowledge and experience too, and it moved my career forward, and provided me employment on the side, full time, concurrently, seasonally, and opened numerous doors, to say nothing of giving me significant advantage when doing studies for new aircraft in which systems were easier to understand.

Maintenance qualification got me my first flying job, my first large airplane job, my first jet job, and numerous other jobs along the way.

Maintenance experience put me in single engine jobs that paid six figures, employed me when I needed it (furloughs, etc), and helped qualify for a degree. Nothing to sneeze at, really.
