Okay, so there is a book called "The Strange Life of Ivan Osokin" and it is about a boy named Ivan who is really unhappy with his life. He wishes he could go back in time and make different choices because he thinks that would make his life better.
One day, Ivan meets a magician who tells him he can help him go back in time and make different choices. Ivan is excited and agrees to do it.
But here's where things get really strange. Even though Ivan goes back in time and makes different choices, his life still turns out the same! He is still unhappy and feels like he is stuck in a loop.
The magician tells Ivan that this is because he didn't really change anything on the inside - he just changed his external circumstances.
So, Ivan tries again to make different choices and this time he focuses on changing himself from the inside out. And guess what? His life starts to get better!
The moral of the story is that sometimes we think that changing our external circumstances will make us happy, but true happiness comes from changing ourselves on the inside.
