There are some languages that I used to learn at school (Russian, French) and at the college (Arabic and Spanish). Now I am learning Hindi and Japanese (cultural interest). I also want to start learning Tagalog as my neighbor is from The Philippines and Tamil (I like Tamil movies).
Do you think it's possible to learn so many languages at the same time and do you have any tips on how to keep all of them active? (I don't want to forget the languages that I've learnt before).
