"What kinds of resources do you use to learn languages?"
Translation:Kiajn rimedojn vi uzas por lerni lingvojn?
This reminds me of the old saying (or was it a commercial?) --- If you don't have time to get organized, how do you have time NOT to be organized.
If you only have da time for Duolingvo, how do you afford not to use your given most effectively by using a variety of methods and resources?
