how do feel when you learn another language?

I'm learning english. The first time I tried it, i found learing english very easy and interesting. This is because when we begin to study another language it's very easy. Then it [inevitably] becomes more difficult. The most difficult skill [of all] is listening.
[Sometimes] I become bored, sometimes I want to give up. But then I think I can do anything if I don't doubt myself.
