Duolingo is the perfect tool to use the 2 min rule with. You just go on and do a couple minutes of whatever language (in your case Spanish) and before you know it, you have a 'language habit'.

You are so right about expectations, and I'm going to cover that in the coming series. You are on the right track, and hopefully I can give you some tools to really turbo boost your good habit forming! :-)
