There is a website called ''easybib,'' it will cite your source, just put the title of the website, book, journal or any other form of writing and it will cite it. Sometimes you will have to add the writer or date of the publishing. The most important things in the mla are: Authors name, date, and title.
Hope i helped!
If you would like I can add the website url in the comments sections <3

What is the author trying to explain
This is a matter of opinion. Although, optimism is important because we live in a world of negativity and pessimism. Optimism is good to see/show because it brings "light into a world of darkness". A lot of people need to see and experience optimism to lift their spirits and feel good about life.
