Hello, Cody! 

My name is Alex. Nice to meet you!

I have a few improvement suggestions for your notebook entry in English.

Introducing myself

I'm learning English, because Here you don't need a comma after the word "English".

I want to make friends from different country,and Here I suggest that you write "countries". If you write "country", it seems that you want to know people from one different country only. Another point is that you don't need the comma between "countries" and "and".

also needed in my job in the future. You are using "needed" (past) and "in the future" (future). It doesn't read very well. I suggest you write something like: 

... and will also need it in my job.

My native language is Chinese, and I grew up in Taiwan. You don't need the comma.
I love singing and a little painting.
Finally,nice to meet you.

Basically, that's what I wanted to suggest you! 

Good luck with your language studies!

Alex.
