I spend my last four months with learning German in DKFA, Munich. I think 20 hours per week is enough to stick my life with this language along time. Of course i still need more time to be able to both write and speak German fluently, but i am good enough already for the daily conversation, i guess. 
Some of my friends asked me which language is more difficult, English or German? I will give a “brief introduction” here to answer the question.
What is the first sentence that you learned in English? It will give so many possibility, but i am sure that two of them are : HOW ARE YOU and I LOVE YOU. So, let us take them for examples.
