What would be the easiest language to learn?

I speak two languages; Albanian and English. Albanian is kind of like Russian, German French. But that is just my opinion. My parents want me to learn Spanish and I do speak some. On a scal of 1-10 with ten being fluency i am probably a 1.9. What language would bethe easiest to learn for me? The most practical or useful? How long would they take? Also, what are some tips for learning Spanish and some good sources and how much time to reach like a 7-8 scale?
