We are all so busy these days that it is a constant challenge to find time to do the things that we want to do, like finding the time to practice your language. It's very fortunate that you don't have to assign big blocks of time to language learning, but you can learn even if you just have a few minutes to spare here and there. That's pretty much how it has been for me. I have an hour long lesson every week, but other than that, I try to get in whatever I can whenever I can. And I also make sure to practice a lot, even when I'm alone, I try to think in the language and speak to myself in the language that I'm learning. It helps.
