I use my fitbit to keep me going... Just gotta pass one more person. I also compete with myself, improving run time. Yesterday I ran my first 14 min mile. Of course the next one was slower and the last one I walked, but I DID IT.
I am an inspiration to others because they notice how my body, eating habits and general attitude has changed for the better over time and I get a lot of questions about how I did it.
Favorite song? My guilty pleasure is disco music, for some reason knowing all the words and sometimes singing along keeps me going when I want to quit.
