If I could only learn one additional language, and I wanted to travel the world, what language would serve me best other than English or Spanish?
I’ve gained a lot in my life learning Urdu and Hindi and encourage more people to learn. They are essentially the same language with different scripts, but unlike Arabic or Chinese they are Indo European languages and are much easier to learn. I grew up speaking farsi so maybe it was easier for me but if you work in IT knowing Hindi is indispensable.
