‘Conditions for’ first, not ‘ ‘capacity to’

Discussing the person who avoids reflection, she writes, ‘When such a man considers a goal or desire he wants to achieve, the first question in his mind is: “Can I do it?”—not “What is required to do it?”’ It’s a handy approach to keep at the forefront. When confronted with obstacles, we can first consider the conditions necessary to tackling them, not if we have the capacity to do so.

That is from Farnam Street, quoting Ayn Rand.
