You are strong enough to overcome all the problems you face.

Count the days this has already been going on. Whatever the number is, you have got through every one of them, including the ones you would have said in advance were not survivable.

That isn't a motivational point, it's a record. The evidence for the claim was never a feeling of strength — nobody in the middle of it has that — it's the attendance sheet.

Strength here means little more than the demonstrated ability to still be here on day forty. You already hold the data. It's just filed somewhere you don't tend to look.
