<p>i think the most important languages to learn will be for those in developing, but growing regions - mainly china (or asia in general) and south america</p>
<p>following that:</p>
<p>1) mandarin</p>
<p>2) spanish</p>
<p>but ask yourself where you’d like to do international business. for me its in asia, so i’m studying japanese, will study mandarin, and already know vietnamese</p>
