First notebook entry: Introducing myself

I am a nice guy, and I want to make friends with foreigners. I didn't have much time to learn it before, which is a pity. The second reason is that I am looking for a job now. Spoken English is necessary in Shanghai, so I must pay much attention to it. This means that learning English is very important after my job in my free time. So I’m under pressure to learn English.
