my daily life
1.
Last night at my office, Me and my coworkers worked overtime.
Although I had a planned to go somewhere else with my wife, I couldn't stop working.
Next week, I am scheduled to go to foreign country for business trip.
Until that time, [I have to end remaining works(jobs).] -Not sure what you're try to say
At 6am, the jobs I had to do were done. I slept for a few hours.
I was exhausted and but I was trying to keep my promise.
My family went to Mask dancing festival in Andong city.
2.
[Remaining jobs were lots]-kind of confusing I think you meant [you still had many jobs left, that still you have to do]
Suddenly I felt I had to organize my jobs in list.
First I listed my jobs, Second I set priority on my jobs.
This was pretty good, with very few mistakes.
Keep trying hard! Bye bye.
