To all, thanks for the responses, advices, and link to resources.
Yes Hokuto, I've been learning hodgepodges of character and was very frustrated by having accumulated such wide vocabularies and not applying to everyday sentence structure.
Thus, I have chosen to take up two styles in learning:
1) continue to build my vocabulary.
2) learning the common words that's written but not spoken.
I feel this method is most productive in learning the depth of the language rather than the linear approach, where as you're just limited in learning the common phrases. However, it's very time consuming so take heed before proceeding... =)
