The end of my holidays

Today I started work. Yesterday I came back to the capital of Spain where I work.
I spent two weeks in my village with my family.
Now I have to start to work to study English... This sentence is not wrong, but it flows better to say something like "Now I have to start working on my English".

I hope you at least had an enjoyable two weeks with your family before getting back to the daily grind*! :)

*"the daily grind = work

The end of my holidays

I got back to work today. I came back to the capital of Spain where I work, yesterday.
I was in my village with my family for two weeks.
Now I have to go back to work, to study English...
