Not sure why, but I am, and always have been a list maker. I have never been able to keep track of things in my head, and always feel better once they are written down for me to see.
things to do
jobs to be done each day of the week... and month
*you name it, I've probably put it on a list
With the wonderful technology provided by the internet, it makes my little habit much easier.
For keeping track of food and water intake, and calories burned (and several other great resources), MY PLATE is what I use.
If it is genetic, I have my parents both to thank (my mother is the queen of lists).
If it is taught... once again, I thank my parents (but worry where the teaching gap is between me and my eldest, who can't make a list to save her life. Literally)
