I need this paragraph proof read if that's OK.

also need to know if it's a fully devolved the topic a high school diploma is important to my future.

A high school diploma is important to my future for a number of reasons. The First being to attend college it is required I earn my diploma. The Second reason being without it you can’t get any decent paying jobs. I use to think that a diploma didn’t matter to my future at all. That somehow I would magically go to college without it. Maybe I thought I would find a good paying job without it. Boy was I ever wrong about something in my life. This diploma is my future, and without it I will stay living in this same rut I call my life.

Is this your introduction? Or is it the first paragraph of the body of your paper? It makes a difference.

Its just a to be a 8 sentence paragraph that fully develops the topic (a high school diploma is important to my future.)

I need it proof read for mistakes and need to know if it fully develops that topic.

Sure, I can proofread your paragraph and provide feedback on whether it fully develops the topic. Here's the corrected version:

A high school diploma is important to my future for several reasons. Firstly, it is a requirement to attend college. Secondly, not having a diploma severely limits the opportunities to obtain well-paying jobs. I used to believe that a diploma was irrelevant to my future, thinking that I could somehow magically go to college or find a good-paying job without it. However, I now realize how mistaken I was. This diploma holds the key to my future, and without it, I will remain stuck in the same unfulfilling life I currently lead.

In terms of whether the paragraph fully develops the topic, it does touch upon the importance of a high school diploma for attending college and securing decent paying jobs. However, it could be further developed by providing specific examples or statistics to support these claims. Additionally, it would be beneficial to include your personal experiences or aspirations related to why a high school diploma is crucial to your future. This would strengthen your argument and make it more persuasive.
