> yet I always seem to fizzle out because in the end, why bother?
This has frequently been my problem. I think maybe I'll learn enough to know it's not relevant or helpful outside some curiosity.
Languages are really hard. As an American speaking English I really get no use from knowing another language. Over my life I've learned, Spanish, Hebrew, French and Japanese. Enough to make sentences, and I forgot them all and never used them except for a trip. Everyone in foreign countries speaks English anyway.
