You can wait for years for a big, red bus to come along and take your professional life to the next level, then two come along at the same time. After eight years of time contracts here in France, I've been offered my position permanently. It's a great job and allows me to travel to pursue other interests (South America, Germany etc) so having tenure would allow me to plan the future even more effectively. Just before the offer came through I found an opening in Vienna which was made-to-measure. I applied and received an invitation to meet them and conduct the orchestra. I don't conduct in France (at least not in my day job) and the idea of going back to being paid to stand in front of an orchestra is very attractive. It would mean us moving to Vienna on a time contract, the family learning German (I speak it fluently) and all that at a period when my employer here is prepared to may me until I retire (which I'll never do). Vienna is sending me some music to prepare, so I'll see how much I like the look of what they're performing at the moment. In any case, I'd like to meet up with these people again; maybe there'd be the possibility of a one-off gig later if I decide to stay here.
Some would say "Stay!"; some would say "Go!" The children would benefit both her and there (there's a French school in Vienna which follows the national curriculum) so the questions to be answered wold be more existential. I've got time before I have to reply.
