I think we, being principled people can make an effective public transportation system. Although we have quite quick transportations like metros, taxis, buses, and etc, we don't use or ride them efficiently because we are not being well-organized. Being organized is; for example; lining up at the left and right sides, not at the middle of the metro door and not trying to squeeze yourself into it. (Once, my mom's sweater was ripped out on the edge while we were trying to get in the train' Shanghai is too crowded') Being principled people can make everything better even we are in a difficult environment (maybe').

Happy Friday, Min!
I agree to what you've said. People should practice the word "discipline". These simple things have a great impact to our lives. If we want our country to be better, it should start from us.

Anyway, please be mindful of the following:
* We used the PLURAL FORM when talking about things in general.
* articles A, AN & THE
* Be careful with your choice of words.
