What's quietly radical here is Schwarzenegger's refusal to separate suffering from growth—he's not saying pain *leads to* strength someday, but that they're the same energy, just experienced differently in time. A runner's sore muscles aren't merely the price of becoming faster; the soreness *is* the becoming, just felt as discomfort in the moment. Most of us waste tremendous effort trying to minimize pain or convince ourselves it's "worth it," when the sharper move is recognizing that present difficulty and future capability are two names for one transformation. That shift in perspective changes how you actually *feel* while struggling through something hard.
