Sometimes I feel I can't handle my schedule and it makes me even I can't handle myself. I was very sick on friday and saturday. The last thing I want to do is sick again because of doing all my schedule. Which one do you think is more important? Doing your things is important too, but it is not important as your health. Because if you sick, you have no idea what to do and you lost the control of your body so you can't even do your schedule.
So make sure you are doing good to your body and yourself!
