"It is very difficult to learn Russian ..."? Well,if you hope to learn any language only by chat,it will take you more time that you think,It´s impossible. You will have to find someone to help you, and that means time, alot of time. Unless you make an effort, you won´t learn any language. It´s only easy for children at an early age,if you are an adult,you will have to work hard! There´s nothing easy ! Try to learn also languages with the same roots than yours, that will be easier.

It's extremely difficult to learn russian anyway.

thank y all for your answer

It depends on the level you want to have. If in a case to say hello, good bye or some simple colloquial phrases then chat is OK. But if you want more then you need to work hard.

Yes!
