An hour a day sounds like a really good idea. I did pretty much that with Polish for 6 months, and all things considered, achieved pretty fenomenal progress - I mean, at the start spoken Polish was completely unintelligible, and now I understand most of what is said in videos on Youtube. Of course, the situation with intelligibility between Polish and Russian is much better than between English and German. Still, it makes me really optimistic about language learning in general... I mean, if I actually decided to follow the same process with Welsh. But... Well, I've got many other hobbies, and I can't quite decide that languages are my priority number one. And it's physically impossible to devote an hour per day to each one of them (while living off more than air).
