Huh. I tend to forget about this, but it may well be that English is actually my most valued skill. As a non-native speaker, I'm really glad that I invested a good number of skill points into English in my earlier life.

Your comment got me thinking -- would I give up my current English skill for, say, high-level moneymaking (automated $3M/year and higher)? So far, I can't say that my answer is a clear "Yes".
