Hi Sam you have to learn as much as you can ...it's an endless process

Well over 60,000. Of course our most important word is "dollar"

Hello, Don't worry. Since you mentioned the so many Chinese characters you will manage that too ;) 加油！

Don't get frustrated. I don't even know them all! Just communicate what you can when you can. You improve quickly when you have a lot to learn but more slowly when you know alot.

Hi... yes don't stop and don't count... just learn every day!
