From Nina:

Here, I walk every day–long walks along the shore and out to the old fort. The wind is strong. I keep walking in order not to face it, but I get to the lighthouse and have no choice but to turn around and lean into it howling around my ears. My face and legs are tingling with cold, almost numb, but my heart beats strong. I am so tired, but I keep walking because I have to get home.

And I too keep putting one foot in front of the other, because I must.  I must.
