Transition words are important because they

Transitions are words or phrases that carry the reader from one idea to the next. They help a reader see the connection or relationship between ideas and, just as important, transitions also prevent sudden, jarring mental leaps between sentences and paragraphs.

for this, you need to remember something significant in your own life, for example, if you were bullied when you were younger, you can mention your memories on this and touch on how such treatment can harm other kids your age either physically or mentally. (racism, car crashes, a parent in the hospital are all very good subjects, think hard on it! )
