First notebook entry: Introducing myself

I am learning English because I need it for my school and my future.
My native languages is Spanish and I grew up in Mexico.
I enjoy playing soccer, drawing, watching movies and eating. :$ Haha. I also look after children.

My native language is Spanish - This sentence is correct. However, it's not necessary to use this sentence. It's more common to just use "I speak Spanish", especially since after that you put "I grew up in Mexico".

"I grew up in Mexico" is a good sentence too, something else that would be more common is: I was born in Mexico (or) I was born and raised in Mexico

I enjoy playing soccer, drawing, watching movies and eating. - playing, drawing, watching, eating: these are actions. The verbs: play, draw, watch, eat.

You could also use "I like" or "My hobbies are" instead of "I enjoy".

Examples:

I play soccer/I like playing soccer

I like to draw/ I'm drawing a picture

I watch comedies/ I like watching comedies

I eat fruit/ I like eating fruits

Like Kaedee was asking, are you a babysitter? If so, you could type something like: I am a babysitter.
