I used to do an yearly letter. It was great motivation when I was able to achieve my goals I stopped it because I had a bad year and everything turned upside down from that time I was very scared to write a letter I'm going to start it again
I'm actually surprised anyone said they would not recommend this product. It's a clear use for this service, and it works as advertised. If you don't like it it's because you didn't understand it's purpose. I recommend it. I just got a letter from myself today. Which was bitter sweet, but I love doing it. I'm doing another one today and I have recommended it to many people.
