Hmn! Dats 8years now. Simeon, it depends on wat U want. If U luv teaching, go ahead wit d PGD programme in Education. If U luv ur Engineering discipline, I'll advice U 2go 4 professional qualifications in Engineering field, and always apply 4experienced jobs. God does all things. One day, it will click. NOTE: Do not leave ur teaching job, until U get a beta one.
