How do I make my thesis statement more specific?

How do you make a strong tie to your thesis statement at the end of paragraphs?

• I'm working on a psychiatry research paper and my thesis is ; "The examination of the job description, education, and business shows that psychiatry is a job that is very time consuming but also very rewarding." My three paragraphs are obviously about the job description, education, and business but at the end of each paragraph I have to link it back to the thesis. Help?

• Answer:

  Just summarise each paragraph and link it back by success in the job, the enrichment you get yourself by learning/doing it, and the possible financial rewards.
