If you find one word in the dictionary, what word would you like to choose and why?

I'd like to find the word "serene". Being calm and quite makes me alive. From the depth of silence, I gain power. As I'm quite talkative in the class, you might think I'm outgoing, but quite the opposite. And...I'm a peace lover. I think being a peace maker than peace lover is more important.

Hello! Guys! I know you're working so hard to settle in the second session. Good luck to you!
My question is~ Would you recommend me the best website that you frequnetly use to learn English?
