I'm not prone to quoting sayings but this ran across my Facebook feed and I thought it really applies to hiking:
“Almost anything can be done if one proceeds slowly enough. Often we are discouraged by the enormity of a task or the length of a journey and become impatient with the difficulties we face. We lose faith in ourselves. Patience reminds us that what is in front of us is just this moment, just this step, just this breath.” — Joseph Goldstein
When I'm hiking all I have to do is take the next step. That's it.
