Which Languages would be most useful to know??

Hindi or chinese i think...... English is good language too. it is very easy to learn or understand. It is not as complicated as Hindi or Chinese.

Not sure what you mean by "here." Do you mean MyLot, or the locations where we live? Where I live, speaking Spanish is extremely useful, as we have a huge Mexican immigrant population. If you wanted to work on the beach, German and French would both be handy. Here on MyLot, Hindi seems like it would be helpful getting around some of the language barrier.

Other than English I don't know maybe french or russian.

I reckon Spanish would be a useful language to know. There seem to be alot of asian speaking people here at MY LOT, but there are so many different asian languages it would be hard to choose which one would be useful to learn.

If you are going to be in Europe, French, Spanish and German will be useful. If you are going to be in India you can manage with Hindi and English. If you are going to be american countries like Brazil, Argentina, etc., Spanish will be very useful.
