Make it a habit to overcome difficulties.

Habits carry people through the stretches where motivation has left the building.

The walk at the same time each morning, whatever the weather or the news. The Tuesday call. The rule about not deciding anything important after ten at night.

None of these overcome anything by themselves. What they do is hold a shape for you during the period when you cannot hold one.

Difficulty gets met by structure far more often than by effort. Build the structure now, on a day you can, and let it work on the days you cannot.
