psychology or makeup?

This is a really random question I know because it's like comparing apples to oranges. Have posted this question on the education forum because I want to study subjects to be able to teach them in further education. Am posting here because it's a psychology related question also. Hope that's ok!

I worked as a beauty therapist for five years. A sudden change in health means I permanently can't teach a lot of the treatments I am qualified in (waxing and massage are too physical) but if I upgrade my existing makeup qualifications, this is something I can physically manage to teach. Teaching evening courses would be advantageous to me.

I am currently doing a PgCert in Sociology because I want to be able to teach that at A level. I have an interest in psychology and see that a lot of sociology teaching jobs request the ability to teach psychology. Would be a pleasure to take up the psychology PgCert offer I hold for next year but I can't afford more makeup training and the PgCert in psychology. However I think psychology would be a good partner to sociology and teaching something more theory based could be a bit less unpredictable regarding my health.

Aww b*gger! I know this question is very unique and specific but does anyone have any thoughts on this with regards to someone who wants to teach in further education. I'd do both happily but it's about money. Like even if I study both in the long run I wonder which might be best to at least use as a springboard into teaching.

Any advice appreciated
