What is a good essay?

A good essay is a something written that catches the readers attention.  It can be anything interesting. Just something that totally engulfs the reader's mind.  It needs to be well thought out, organized and coherent.  The writer has to know what he or she is talking about.  This will convey the essay and essayist as credible source.  Also it is a must for the writer to care about what he or she is writing about.  It forces the writer to be passionate about what they are writing about.  And when you care about what you are writing you are going to do your best on it.  Also if you care about something a lot you will put in the time and effort until you think it is totally one hundred percent satisfactory.  To write a good essay you have to be knowlegdeable on the subject.  If you are not in the know about the topic you can't really call it a good essay.  

  In my essay I need to write more cohesive.  Many of my thoughts ramble on and are inchorenet at some points.  Also I want to write more to the point.  It would make my essay better and more readable.  I may need to care a little more about what I am writing about.  To make my essay better I need to have a solid thesis or topic and this would make my essay more coherent, easier to read and just better in the over appearance of the entire essay.
