What can be said? Learning a language is rough work, with difficulties in correct pronunciation, or at least good enough that someone can understand what you are saying. Not only that, but you must master sufficient vocabulary to give yourself a chance at being able to enter into conversation in the first place. And finally, Grammar. 

It seems that Duolingo is a good place to begin with vocabulary. After which, start reading books away from the app to increase understanding and pick up more vocab. while learning to recognize standard sentence structure. 

My goal is simply to pick up vocab. little by little. At this point, there is virtually no chance that I will ever use it with a native speaker so, just for fun.

Do you have any Graded readers that you, the listener, can recommend?
