Be aware of the vocabs!

Why should be aware of them? Vocab is one that integrated in every expression spoken or written in your communication tools. Right word would give better understanding. So, one doesn't need many words to say one thing through the right choice of words or one can put others at ease by using the right words in commenting or giving order. Let's compare: "You must change your clothes now. Find the brown one."  with this: "You'd better change it with the brown one, it looks good on you." Or, "I enjoy it", instead of "It gives me much excitement."

It's just a simple sample, I am sure you can find other and more samples that used in your daily communication.

English should be treated not only as a language for academic purpose (like used for school, campus or research target) but also a language for International Communication (like used for conversation, chat, sharing and emails). One should learn English both in serious and fun ways because in the real life ther will be a moment when someone would use it in either formal or informal setting.

While in learning methods, the one can find the best and the most suitable method that matches with her/his preference for studying it. Although one can speak or write freely with no much attention to the grammatical usage, but in one moment, the would need it for the appropriateness and better understanding in communication.

So, never stop learning, be fun as well, especially when dealing with improving the English communication skills.
