There's a difference between knowing my limits and letting fear dictate them. I spent years confusing the two, honestly. The body knows the difference, even when the mind is screaming. The trick is learning to listen to the quiet wisdom beneath the noise, the ache of true overreach versus the thrum of "what if?" The tight chest of anxiety versus the heavy legs of real fatigue. I used to push through both equally, thinking it was all just weakness to be conquered. Now I know the difference, and honoring that difference has been the key to going further than I ever thought possible.
