It's taken me a long time to become conversational in Spanish. I'm still far from fluent, but I don't find the grammar difficult, though I haven't delved into intricacies like gerunds and such -- my main thing now is expanding my vocabulary.
Just as with my native English, I don't feel that there's an end-state; I'll always be learning more about it.
