Diary 2011-3-3 Yesterday was a busy day

Yesterday was a busy day.
Since you are describing the events of "yesterday" then everything that follows should be in the past tense.  That means that "have" must be "had".

 I felt so tired. I have to modify my thesis and print my thesis in a short time so that I could hand it in. Meanwhile I have to attend a meeting so I was in a hurry. When I printed my thesis out, I found that I had made some mistakes so I have to go to the shop to print it again. You couldn’t imagine how many times I have gone to the shop.
When I finished my thesis I found that it was so late. In order to get to my company I decided to take a bus to ShaDun then transferred to a motorcycle. But when I was standing at the No.41 bus station to wait for No.41 bus I found that I it was so dangerous for a girl to take a motorcycle which was driven by a stranger so I gave up going back to the company and made up my mind to go back tomorrow.
It was so such a special day and I also felt that it was also a fulfilling day.
