First notebook entry: Introducing myself

Hi, 안녕하세요. I am learning English and Korean now. Why English? because I wanna (or want to) study about Gastronomy for my Master's degree in Boston University, I think I have to improve my English, especially for communication and writings. I also wanna (or want to) make friends w/ ppl (or with people) all around the world, and English is a  universal language, that is a kind of a core of language you have to speak. and why Korean? I love culture and food, and I think Korean cuisine and culture is interesting to learn about, so I decided to learns both of them.
I was born and grew up in Indonesia for the whole of my life, so I am an expert in Bahasa Indonesia (or the Indonesian language, or just Indonesian). I love cooking, singing and travelling and watching movies also!

Very good. The mistakes you made are small and typical ones that Indonesians make; but it was all understandable. The bits in orange are more formal (Exam English) but as the piece is informal they don't matter too much.
