What do you think of this book i'm working on?

It is a true story, inspired by a time in my life that I'll never forget. A little kindergartener, inspires someone to change their life, makes him realize his career path should be a teacher. The true story behind it is that there was one day at a school I work at, a little girl was upset, I told her, that I would spend time with her during lunch recesses,and she ran into my arms and said,"you're the best." they had a carnival at the school last week,i helped out,and during lunch,she walked over and gave me half of a carrot,and i helped in the clroom,she wrote I love you on a piece of paper.A little kindergartener made me want change my life around,she made me realize my career path,she took my heart,and inspired me to make it into a novel.i think it'll make a great book. what do you think? is it a good idea for a book?
