I think you should write it yourself. We can start with the pros and cons.

The first is about making friends. For example, you can write that those who were originally poor made friends, they helped each other and made progress together, and then made achievements, rewriting his original life and making his life more dazzling. There are many such examples, but you should choose some novel ones. What a speech needs is attraction.

The second is to write to a bad friend. You can write those excellent ones, because you make bad friends, and then gradually deteriorate, and finally ruin your future and even your life.
