What if this experience changes me for the better?

I went snorkeling for the first time in October of 2019. At first it was scary. I could not get the breathing thing down. I kept on trying and then I relaxed and everything worked. I soon enjoyed looking under the sea. If I did not push past the scary point I would not have swam with a manta ray, turtle and school of fish. What an amazing experience. I did feel like little mermaid. It has changed my life for the better.

What experience have you had that has changed you for the better?
