Heart of the Day

It seems that days are like a watermelons. There is a part of a good ripe watermelon called the heart. It's in the center of the melon and it is the sweetest, most juicy part. It's the part that's easiest to get to, and has the fewest seeds. 
I know this may seem like a stretch, but days are like that. For me, the morning is the heart of the day.
The phone hasn't started ringing, most chores don't have to be done until later in the day. The air is usually fresh and cool.  And, my mind is clear of debris. 
I have to be very protective of the heart of my day because it can easily slip away. Poor planning, lack of focus, or you allow someone to lay claim on it.
Fortunately, the heart of Jilda's day, is a few hours after mine. She is NOT a morning person. 
I was a little slow on the uptake on this and it almost cost me my life.
"I'm not sure what happened officer," she would explain. "But he was all chipper and bubbly before I got the first pot of coffee down, and I just snapped. I cut his head off with a paring knife."
"He tried to talk to you before you had your coffee?" the policeman would clarify. 
"Yes!"
"Well this is a clear case of justifiable homicide boys, lets wrap this up and go have some doughnuts." 
Anyhow, now that we've been together for thirty six years, I know to keep my distance and keep quite until the fog lifts from her eyes.
I use the heart of my day to think, meditate, write, edit, and other tasks that require energy and creativity.  I'm more productive then. 
So, how do you use the heart of your day? I'm curious.
