Closed Job Doors?

I am slowly starting to put out my feelers into the job market in Berlin, in preparation for my youngest starting kindergarden in the fall. My "strategy" this time is to rely on my network here. We'll see what it brings. So far, I have let only a few people know that I will be looking for work. I'll increase the radius to more random contacts as time passes. Today I had an informal chat with a think tank based here. They do interesting work, but I found it difficult to convince even myself why I would want to work for them after the World Bank and UN. To be honest, because I have a husband that works full time and travels a lot, because we have chosen to live in Berlin, and because I have three kids. My career self has not yet quite accepted that all options are no longer open.
