Think of transitions as Hanzel and Gretel’s breadcrumbs; they help lead the reader from one point to another. Without them, the reader gets lost and confused, and when the stumble on to your next paragraph, they wonder why it’s there.

The problem: The inneffective introduction:
is not organized by key points
is too long and becomes repetitive, losing the reader’s attention

The solution: The effective introduction:
is organized by a thesis listing the key points
is brief and concise
