I don't recommend reading stoicism. These are very old text and they are rather abstract. Most people don't think in abstractions. Also this is not a philosophy which fits everyone. However, history is the same play again and again. If you're into philosophy the next step is religion which is applied philosophy. Philosophy of very different people can be confusing. rather read in the life of saints. Even if you're not religious, this is easier to *get* and their stories are more entertaining IMHO. You can even read some of the stories to a child. There are a lot of different saints lexicons. I'd recommend Prologue from Ohrid: https://westsrbdio.org/lives-of-the-saints-from-the-prologue-of-ohrid/
