Strength is relative, but the principle is universal. If you want to get stronger, you have to push beyond your current limits. The same is true in business, leadership, relationships, and life. Almost everyone says they want to grow, but far fewer are willing to do the hard things that make growth possible. You don't build capacity by staying comfortably within your limits. You build it by lifting heavy shit, then allowing time for recovery and growth (rest is key!). If life feels easy, maybe it's time to self-select into something hard.
