Dear Pat,
This is your 18 year old self. As you probably remember this wasnt an easy time for you. You were going through a lot of bad things and it was hard to get through it. Right now your work ethic isnt where it should be. Hopefully when you read this note your work ethic would have changed and gotten much better. Im sorry I had to go through this stage but I promise that it will only make you stronger. Anyways, I hope that all is well when I get to be your age. I hope by then I have something to look forward too in the morning. I hope by now you have a wife and maybe kids. But If not, I really hope you are happy and I promise that i will do everything in my power to make sure that you will be living the good life by your age.
Sincerly,
Your 18 year old self
