I work in Dubai. I work out of Dubai. These are similar (the work is in Dubai) but the second further clarifies that the work done has an impact beyond Dubai, probably globally from the context. I ran a business out of my garage. (The business was located in my garage but had customers from a much larger area.)

I think so. I think this is the framework: You put work into some activity, and you hopefully get some benefit out of it. I get a lot of pleasure out of playing with my grandkids, for example. They achieved a lot. They got a lot out of their activities in Dubai.
