June 16th I made a mistake the other day. I misunderstood the date to have to fill in, and I wrote another dates down in the forms. This problem interrupted my colleagues' work. I didn't think I made some mistakes, and my procedures was made by asking my colleagues. This issue beat me down and I felt depressed the other day. Yesterday I consulted for my senior colleague in another department, and I felt better than the other day. Although my works would be late, I will check my procedure again for while.
