Degreelessness Purporters, Oneness at University and At Least a Postgraduate Diploma

I know someone who has been stalked and targeted by a gunman, (possibly unrelatedly) because of not having studied a complete Bachelors, Masters (or at least a Postgraduate Diploma) or PhD degree in that chosen field while outside University, working in that field (Education and Music), showing that short course sequences and Vocational qualifications by themselves didn't support his (famous) pedagogical requirements.

What to do?
1. Not work in fields that one hasn't studied a degree in, or:
2. Study a degree in a field one will work in.
3. Something else.

There is a rhetorical piece of advice that one should follow "oneness" (one field) at University.  This would avoid needing to write a medicine A for each sentence one writes in a Research Masters or PhD when one has no coursework qualification (or at least 250 medicine breasonings, or other per chapter), to avoid medical problems studying a field by itself might bring.

For example, try a Graduate Certificate Of Commerce after Honours, then transfer to at least a Diploma of Commerce.  Have teachers teach courses for you and avoid public music performances, particularly on negative themes.  An undergrad degree in Music (to reactivate Concerts) might seem easier, but you will have to weight up whether to use more undergraduate credit or study Masters which needs medicine if you have no coursework background.

P.S. Children are seen as taking it back.  You can too.
