I totally recognize this voice. It's the one that always tries to make me walk. This voice, let's call it Lazy, has all sorts of interesting arguments on why I shouldn't run:
Lazy: "it's ok to take a break.
Me: No, it's only been 2 minutes. This is only 5 minutes of running. I've run a few marathons. I can do this.
Lazy: You just had a baby
Me: 3 months ago.
Me: it's just a little hill.
Lazy: Don't you feel that tightness in your knee. You can injure yourself if you push too hard.
Me: I'm not pushing too hard. It's 5 minutes and I'm running a 12 minute mile.
I keep pushing until the street starts it slight descent down. Lazy becomes blissfully quiet. The more I run, the quieter Lazy becomes.
