How do I add a dictionary like Rockyou?

Hmm I see I see

But that does mean I'm on the right track with my current command, right?

Once again, thanks a lot for taking the time to explain all this to me!

Yes, your command line is fine. The algorithm is meant to be slow so that it's more trouble for crackers. Moreover you are using the CPU and not the GPU. If you do simple dictionary attack, it might finish relatively fast but as soon as you add rules, it becomes much slower.
