Easy Never Works

Why is it easy never works for me?  Yesterday was a great day to be out painting.  It wasn't too hot but the sun was shining so the lighting was perfect.  It was an absolutely perfect day to be outside painting.  No stresses whatsoever.  What happens?

This painting is mediocre at best.  I see a lot of issues with it.  It seems that I need to be distracted to paint well.  If there are no bugs, or wind, or hot sun, or snow I tend to overthink what I am doing and try for perfection and that always ends in disaster.

We leave Thursday on a canoe trip and I am going to try acrylics again.  That should be distracting enough.
