I enjoyed reading! Great job, I completely understood your notebook entry. I simply rewrote your entry to give it a little more ‘flow’ and corrected a few mistakes.

Little tip: make sure you are in the correct tense when writing!

     Today is Saturday, and I am so happy that I can enjoy the weekend! I can do whatever I want. I think there won't be lots of people going to work by subway, but when I took the subway home this morning, I was wrong. There are so many people in the subway! Some guys nearby caught my eye, they are wearing ties. They must have an interview, so they keep to themselves. It seems that everyone needs a tie now. 

     Another group of young men are leaving school to enter society. They will face new things to study, new jobs, and new friends. However, they will face a lot of challenges. I hope that every one of their dreams comes true. Seeing these young men reminds me of the past, and my first interview wearing a tie. It feels like I only left school yesterday, but so much time has already passed.
