I'm currently learning Chinese (using Remembering Simplified Hanzi from Heisig [0] for characters and Iknow [1] for words/pronunciation) and I find it a lot easier than I initially thought it would be. It helps a great deal to know that all these characters that look so complicated are mostly made of the same 200-some radicals [2], suddenly it's a lot less daunting and the characters even make sense most of the time. And sure, one might forget characters with lack of use, but the same can be said about other languages. Grammar is a hot topic on the internet, isn't it?
