I'm learning Spanish right now. It's fairly easy, but granted I do know English and Polish already.
Next up after Spanish, I'd have to agree with other posters and say Chinese.
Why? The population is the largest in the world and it's a rapidly growing economy.
Not to mention the potential for opening a business there is great.
Although I think learning Spanish first is important. Connecting with a huge population in Central and South America, as well as being able to learn Portuguese easily for Brazil.
