my today

Hello all.
Today was like many other days, but it was some unusual things. For example today I woke up a half hour early than usual. It was at 5.00 am because my eldest son risen for long trip to boys camp.
After that i go to work like i do it everyday. Nothing extraordinary happened.
But later i understand that today i did my work very quick, and can finish and go home earlier than usually.
In that case i can spend my evening at the computer and improve my writing.
I hope that tomorrow i will have some time to improve my English.

I will be very gratefull for your help to correct my first experiense in writing.
