You'll always be able to teach oversea. I assume age isn't a factor for this type of job. On the other hand, you probably won't be able to earn money in software engineering 10 years from now if you leave this path. Without skills in 10 years, it's likely to be much harder to make money than now. It's always good to have a safety net.

But you can also be a gambler and listen to your heart and leave tomorrow!

Now that I think about it, right after I graduated (from a top school in my country), I had several options to earn a very good salary. 20 years later, those options simply aren't there anymore! I'm too old for a beginner position, and don't have the experience for a more qualified job.
