I know how I gained 24kg in 2 months. I ate too much. It is weird though. I worked so hard to lose 60 kg then I was able to simply "forget" all my effort. How does one forget?
I also "forget" to keep in touch with friends and loved ones. I'm terrible for that. I never forget to tell my son I love him but sometimes forget to tell my wife. I never forget to pay my mortgage but do forget to wash and service our vehicles but never my motorcycle.
Later today I am going to search the words "forget" and "focus" on the net. In my world, I suspect they are connected. To Forget - is like losing focus?
