They say English is the hardest language to learn. For native English speakers they say Asian languages would be the next hardest as they are very different from English and European/Romance languages. Spanish/Italian/French, etc. would be relatively easier since they can resemble closer to the English language. Any and all languages are hard to learn. At the end of the day though it always comes down to the person. People can pick up other languages, no matter which one it is rather smoothly/quickly. While some can be much slower and have a harder time. With enough effort and motivation though anyone can learn any language. :)

I can read many texts but my prounounce is very bad!!!

I think Russian seems difficult but you speak it so it must seem easy to you! :)
