Crossing the threshold

The debate starts at 5:15 a.m. when my alarm sounds. I made a commitment to myself last night that I'd swim at 6 a.m., as I do every Tuesday. I meet my friend, Susan, there, and we do laps and challenge each other with springs and laps.
I didn't confirm with Susan last night, so, as my alarm goes off at 5:15 I tell myself that I can just sleep in and tell Susan I didn't hear from her last night, so I wasn't sure if she was going to go. How awful is that? I would blame her for not confirming with me. It's not her responsibility!
Susan sent a text to me around 5:25 a.m. She doesn't drive and she wanted a ride. She gets ready at the gym, and this morning she was wearing a suit that she didn't want to wrinkle on her bicycle.
"Sure," I replied. "I'll pick you up at 5:55."
Thank goodness for friends and accountability. Had I not heard from her, I would have slept in. Once I cross that threshold from sleep to up and at 'em, I'm fine. In fact, this morning I had the best swim I've ever had! I swam a 300 in about 10 minutes, which is the longest set I've done. It's 100 meters shy of the Tri for the Cure, which I really struggled to get through in 17 minutes.
What is it that is so difficult about crossing that darn threshold from those comfy sheets and cushy pillows? I lay there and debate with myself and I remind myself that once I get up and get moving, I'm going to feel better and enjoy the swim. I'll feel powerful for having started my day with a swim and resistance training.
But these sheets feel ssssooooooo goooooooood.
It's like the first dip into the pool. You know it's going to feel cold. It's going to wrap your body and chill your skin, and your jaw is going to tighten as you brace yourself against the cool temperature. Then once you get moving ... it's nothing.
Thank goodness for my fried, Susan. Thank goodness for accountability. Thank goodness for my To Be Re family.
