There seems to be a small probelm getting 'jobs' when moving around to the bases, or losing your career.
A career is what you want it to be, so don't think too big. You don't have to work for a big corporation.
Don't get me wrong, I admire those who have their careers and want to stick to them. Do what you need to do. This is merely some suggestions for others who want to start something new or change venues to follow their spouse/partner.
Maybe my definition of 'Career' differs from most, but there are qute a few jobs/careers you can have from your own home.
An example is 'Medical transcription'. My mom is working at this now, and doing great. Everything is done over the internet, so they don't care where she is living (she is in Ontario, she works for a US company and her accounts are from the southern states and Alaska).
This is one that I am seriously looking into.
Other areas seem to be 'normal' everyday services that most take for granted.
Such as:
Childcare - daycare, babysitting, tutoring...
Pet services - grooming, training...
Exercise - Yoga, Pilates, martial arts...
Beauty - Nail tech, Hairstylist...
There are probably a longer list of others, but I can't think of them now.
Most of these can be done out of your own home, so no 'rent' for a separate building. For exercise interests, look into renting a chuch basement/gym.
These are just some areas I've noticed from other threads on this site.
