(Another Rosetta Stone question): Is there anything you wish you had approached differently when using it?

I’m nearly halfway through the first level, and I’m very much enjoying it. Because it’s the second language I’ve learned, I’m fighting the urge to try and understand every little conjugation and grammar—it’s making me realize that I really like to be in control of what I learn. Is that a mistake?

For those of you who have completed Rosetta Stone, did it work better if you just allow the knowledge to come to you?
