If I have a chance, I want to ask childrens = the children, That 'Do you have a dream?', If you don't have any dream. First of all try to find your dream out. It's hard to find your dream out. Even you spend 5~10years. But It's the most important things in life. Studying hard isn't the first thing. It's the second thing. Find out What you want to do. And then study hard How to be that or reach there. I just want to say to childrens like this :)

Dear Mr. Kim,

Hi, good morning! Thank you for answering your homework today. Your idea is correct and I agree with you. Oucch,, that's one thing I didn't do when I was still a kid, I didn't know what I want, all I know is to study to have a good job someday.That's what parents usually do here. Your idea is brighter that anyone does, first is, you have to know your dream and then work for it while you are young because you have so many chances and years to fulfill your dreams.. I'm already 31 years old now, I want to become a flight attendant but I didn't work for it, maybe if I believed in my dreams when I was younger, maybe I'm a flight attendant now traveling to different parts of the world. 3 claps for you Jonsoo! Now, I stick with the (YOLO) YOU ONLY LIVE ONCE. That's why I'm working hard and still hoping to travel before I gone in this world.. huhuhuhu.. What about you? What is one thing that you want to do before you leave this world? See you later  :) 

Marian  :D
