Sure. Spanish is also a good choice. I could have went on and on enumerating interesting languages and interesting reasons to learn them (like reading history, philosophy, or great literature in their original form). As for your second point, as far as I know, Romanian's ties to Latin aren't only reasonably strong; Romanian is actually the most like-Latin language that is still spoken -- however, Spanish and French s…
I think any language is worth learning. Right now I'm at 5, Dutch (my mother tongue), Polish, German, English and French (the latter poorly through inactivity). I very much want to learn more languages and I find that with every language added the next one becomes easier. So there is no such thing as a language 'not worth learning', almost all of the languages spoken on the European continent are related in some way…
However, I don't share it. I believe that one should spend most of one's time trying to do something awesome in one language -- as opposed to wasting time by learning 5.
Now, don't get me wrong, the fact that you now 5 languages is very cool; however, I don't think I'll ever use up that much time to gain those particular skills.
You see, I believe that if one were to draw a graph illustrating the relationship between the "awesomeness" of what one has done and the effort one has put in, the effort axis would be on an geometric scale, while the "awesomeness" one would be on a linear one. In other words, one has to put in a hell of a lot more effort to get something just a little more "awesome".
On the other hand, maybe learning languages is an integral part of what you "do"; or, maybe, it helps you relax.
Either way, and as in most arguments between somewhat-intelligent people, I think we're just going to have to agree to disagree -- please note that I'm using the "somewhat" prefix as it pertains to me; I'm pretty sure that you're just plain intelligent.
Oh, and: Merry Christmas. And a very happy New Year.
