Yes. It's all about opportunity cost. Limited time.
You've gotta enjoy these sorts of things and not do them for the sake of doing them.
I have no desire to do things to have a good CV or to look impressive. I just want to have fun and be stimulated.
I love learning.
Others that I was considering.....
1) Chinese - will be big in the future. But why do I need it? I don't want a career. I don't need to impress anyone. Plus the effort required would be too much for too little reward.
2) Spanish - Practical, widely used language. Probably my second choice.
When I am making some real good money I am going to spend some time in Italy. Go all over. And spend some time with family in a nice little village. Would be awesome to speak Italian over there.
