What I really want to do at degree level are one or two of the following subjects : psychology, philosophy, maths and economics. How do I go about choosing???

My future career interests lie mainly in arts – writer/biographer/editorial work, or in the socially-related field- counselling/psychologist/teaching/probation.

Certain scientific/investigative jobs – experimental or developmental psychology/urban or regional planning/speech pathology/archaology/anthropology – are also interesting to me, but definitely not Business, Sales, Transport, Finance, or Corporate type jobs.

What subject combos of the above are also best in terms of occupational outlook w/o need for immediate further training in a masters/phd??
