When I start my run, I run on Motivation.

From Determination to Satisfaction

When that's all gone I run on Determination. Halfway I change to Satisfaction, for having gotten so far, but that usually doesn't last long.

Running on Stubbornness

Then I run on Stubbornness for a long time, and the last miles I use all the Adrenaline and Annoyances from the day. Those are the miles I run the fastest.

I'm full!

And in spite of the fact that I have used up a lot, I'm full after my run! Full of energy and good feelings!
