How many paragraph should a good cover letter for a resume be?

I believe a good cover letter should have no more than 5 paragraphs.

1st paragraph - Introduction. 1-2 lines where you say that you're applying for this job position

2nd paragraph - Tell a short story where you show off a valuable skill that the employer wants. The story should be no more than 4-5 lines. It should show a before and after picture where you tell what you did in order to solve a problem, save the company time or money, etc.

3rd paragraph - Another short story about a second skill that the employer would want their employee to have. E.g. if you told a story before about how you saved the company money through your problem solving skills, then in the next paragraph you can talk about how you built partnerships.

4th paragraph - A third skills story.

5th paragraph - Close the cover letter with a strong CTA. Again, no longer than 2 lines.

And you're done!
