Learn as much by writing as by reading.
Writing is really different ... it's a way to express one's self. Expressing yourself in such a way that your message gets across and received properly. And understood properly, too. Sometimes when we write (or say, for that matter) something it can get muddled in the translations.
Reading is different because it's like you're just a spectator. All you can do is just watch and take it all in.
Giving and receiving. :)
