Visiting a recycling store that I haven’t yet been to, I walk away with 8 foreign-language books in Bulgarian, Hungarian, Thai, Norwegian, German, Japanese, and Czech. Some might say that this is overdoing it.
No doubt I’d make faster progress if I concentrated on fewer. But is that so important?
I maintain my motivation by remaining interested. I love to dabble. To have dozens of books about keeps me keen. And besides, I’m more interested in developing my language-learning method than in learning languages as such.
It’s a question of balancing my drive to collect with my urge to invent.
