How to Grow Your Newsletter

I found with my newsletters I'll write something in let's say five weeks ago or ten weeks ago and I have no idea what I wrote about. It just speaks to our memory and that's why like putting it out there is so valuable because you have something to refer back to of where your interests were at a certain period of timewhat you learned. One thing I was thinking about doing is that actually taking those lessons that I learned in the past and trying to like rewrite them today and see how much better I can improve them  is something I would like to do but no definitely I feel that like in just one year you don't really realize it from on a week to week basis
