Translation of inefficiency in Spanish

I thought it was great to hear from you. I would love to help you to learn Spanish. I'll write in English and you tell me the Spanish translation. I think that you're good enough for that exercise.
I was born in 1967 in Zurich, Switzerland. It is a small city, but not as small as Basel or Geneva. I grew up in a suburb of Zurich. When I was 12, I moved with my parents to Spain.
To answer your question I'm a college teacher but I am working now for a real estate agency. I'm also responsible for the finances. It's a very lucrative business but I hate it, most of the time.
