Take a moment to consider this seemingly straightfoward question: What word would you use to describe the opposite of "fragile"? "Resilient"? "Robust"? "Unbreakable"? By definition, something fragile is "easily broken or damaged" when subjected to stressors, pressures and volatility. Conversely, words like "resilient" and "robust" merely suggest the ability to withstand or resist shocks. What they don't adequately capture is the ability to actually get stronger from the adversity.
