The reader needs to see that there is connection. Make any corrections. When you are please, share it with someone whose writing you respect. Get their impressions. They are important.
Writing is communication with an audience.
Once that audience is defined, you need to learn what is important to that audience, not just to yourself. Then and only then will you be successful. Do not give up with just one try. Write on many topics, just writing the introductory paragraph. You will find that the process of following the format and thinking through and good introduction becomes easier with practice.
