do you have some good advice?

Happier

I am also in your situation,  I am not for twelve hours, just eight hours for one day, several days I work for day shift, I also have night shift, It makes me very tired, Now I decide to quit this job, I want to find a regular work, When I find it, I think I will have enough time to do what I want to do! To learning english is themost important things for me, I want to blurt out and make me more confidence.
