Everyday life - My ROUTINE

Hello my name is Silvana. I'm from Argentina. I live IN a little PROVINCE to THE North of Argentina. It IS called Jujuy.
Everyday I wake up at 7am but I dont get up UNTIL 7:30am.
I have a shower then brush my teeth and comb my hair
I get dressed and I leave FOR work. When I arrive AT work I have breakfast with my WORK COLLEAGUES 
I work in A financial company. I have A LOT OF CUSTOMERS IN THE MORNING. I like my job.
In the afternoon I have lunch and later ON I go to University. I'm studing BUSINESS Administration. This year I wil finish my COURSE.
At 5pm I return to work, the EVENINGS ARE quiet in my job.
Also I work IN a gymnasium, Tuesday and THURSDAY EVENINGS.
I'm A fitness Instructor and A personal trainer. I have a lot women in my class. We HAVE A LOT OF FUN.
When the weekend ARRIVES. I try to rest and study. Sometimes I go ON NATURE WALKS with friends, I love TO walk in the mountains.
Sometimes when i don't feel tired, or DONT have THE energy, I take salsa CLASSES or tango CLASSES.
I HAVE A BUSY LIFE BUT I LIKE IT! :)

This was very easy to read and no english speaker would have had any problems understanding what you were saying. These are all grammatical and spelling changes but your English is an excellent standard. I have done this as the lady who did the previous amendments is from the US and sometimes UK English and US English is slightly different i.e colour (UK) - color (US).  

Hope this helps!
