When you work it seems impossible to keep on learning and your (little) extra time is for your friends, relax, movies..
After my HSK5 i was about to stop there because i thought i could not go further. i tried so many school and teachers but nothing really worked. Fortunately i had the push i needed to reach the 6th level. I have all this to my wonderful teacher, so professional and patient. Although i was tired and distracted, my teacher has been capable of making everything easier. i enjoyed all the classes i had and now back to my country i just owed her a huge THANKS!!
if you need help with your Chinese, that's what i can suggest you because that is what i experienced..
