What do I get in return for taking notes?

What do I get in return for all the time and thought I put into taking notes? I mean, I put a lot of thought into it. What's in it for me? I've been meticulously recording my meals since December. I can tell you how many times I ate fast food or had pancakes for breakfast. Big whoop! There is almost zero lingering value in doing it other than that it's neat. Is "neat" enough to justify the effort it took to set up the logging process and the ongoing effort of recording every meal? It's fun to set up, but if I'm honest, it's not useful. I don't need more excuses to play with my note-taking tools. I should stop doing it.
