courage to walk this path of life?

The road is not straight, nor is it uniform, nor does it look or feel the same.
There are curves, potholes, hills to climb. The flashes of day and night make the experience itself vary. And things don't just change on the outside, they are also constantly moving on the inside: thoughts, memories, physical sensations.

Early on, there was no thirst, for example, but after a couple of hours of travel, there was. And so it is with every experience, inside and outside of us. From where do you find the courage to walk this path of life? With what company?
