Anna Karenina principle

Hey there little buddy! So, have you ever heard of a book called Anna Karenina? No? Well, it's a very famous book by a man named Leo Tolstoy. Now, in this book, there's a woman named Anna Karenina who is having a lot of problems in her life.

But, there is also an idea in the book that has become very famous. It's called the Anna Karenina principle, and it says that for something to be successful, all of its parts must be successful.

Let me give you an example using a farmer who grows crops. If one part of the crop, like the fertilizer or the watering, isn't done correctly, the whole crop won't be successful. It's like a chain, and if one link in the chain is broken, the whole thing won't work.

So, remember that the Anna Karenina principle says that for something to be successful, everything has to work together and be successful too. Makes sense, right?
