Language learning

How many languages can you use well,two, or more than ?
For your first language , mostly people don't have much about it.
However, for people who learn the second language ,
they face more difficulities than before.
In order to learn better what can we do to imporve it?
These are several things which are important for me to learn language.
The first is practicing, practicing and practicing.
The longer you use and memorize the much you get.
Personally, if some new phase and words that I don't use them
when the time pass by. There're merely few I can recognize.
There is no best way for constantly keeping them in mind.
Secondly, is willing to make mistakes.
Somethimes, you get a new phases and words but you still have no ideas how to
use them properly. Don't be afraid but to speak it out or use it.
When people correct it for you , you get more impression for them.
Afterwards, they become yours . Why not be a fool for a while that you can make you smart .
The last one is have a good self-image and lots of confidence.
I guess I am lacking of self confidence .
Actually, I don't think my speaking is very bad .
However during the conversation if I lost my confidence I will speak disorderly.
Now , I try to build up my confidence , if I can overcome this .
I can truly say , yes , English is my second language.
