Joining in on your journal.
You know, one reason I love reading journals is for those moments when people share their failures. Because, if we are honest, it happens to all of us. Those days when you just don't want to do it and then sometimes you don't. BUT and this is the important part, you learn from that and you learn that when you are open and share it with other like-minded encouraging people, they prop you up and make you want to do better the next time. Keeping a journal is great for accountability. There has been more than once when I wanted to skip a run that part of what got me out of bed in the dark and cold was that I didn't want to admit to skipping the run on my journal.
Learn to listen to your body too. It takes time sometimes to differentiate between tired and sore (which you can push through) and pre-injury (don't push through!), but in time, you can learn to tell the difference - at least most of the time. You are doing great and I'm excited to read your continuing journey.
