Bhagavad Gita, Chapter 7, Verse 11

Of the strong, I am the strength devoid of desire and attachment. I am, O bull among the Bhâratas, desire in beings, unopposed to Dharma.

Real strength here is specifically the kind that isn't tangled up with craving or ego.

This draws a real, specific distinction. Not all strength or drive is pointed to here, only the version free of selfish desire, showing that the quality of the underlying motive matters as much as the strength itself.
