Sometimes I don't have a lot to say in my journal either, however, it does help me stay accountable. I try to write a little something in there everyday so that I can go back and look at my journey in written form. Some days I just need to read my own excitement about MF and my own desire to get this weight off once and for all. I think each of us can be our own best motivator, just by reading our own thoughts. So, I encourage you to write in your journal.
I'm sure you'll hit that 20# club in no time.
