Tue and thur are not my productive day.

Well. Another update for this week.
As I states in the title, Tuesday and Thursday are not my productive day.
So, I did not do much work yesterday.
The main reason I believe is because I usually work hard on Monday and Wednesday, lols, at least for this semester. I have three classes on Monday and Wednesday (used to have four but I withdrawn a course). I usually got out of my dorm in the morning and got back at night. Afterward, after having my dinner, I would like to work on projects, do some study and end up go to bed like 3 in the morning. And on the Tuesday and Thursday, I will have a morning class around 9. So I usually came back to dorm after class, got something to eat and then take a nap...and do this and do that...I always end up doing nothing related to my course works on those two days.
Ya, yesterday was like the same routine. I felt bad especially I got so many works that are pouring in front of me.
However, I do not know it is a personal problem or not. I sometime just have a tendency to not doing any works, specially when I got a lot to do. Very ironic right? However, I just could not understand why some people are able to get so focus and concentration on the work they are doing. They would not even waste a moment to be lazy. I wonder how they can do it. Do they have nothing else to care about other than the work they do? From time to time, I just stress by people who would not stop from working...
