Hardships
If we sail through our lives with relative ease, then when we are faced with a severe challenge, it makes sense that we would not have the tools to surmount the obstacle. These tools seem to come in skill and aptitude both intellectually and emotionally speaking. If we spend our days continually facing struggle and adversity, then like lifting weights, we can, if we choose so, become strong. When faced with a challenge, we must not only solve it intellectually, but there is a certain amount of grit, or tenacity that needs to form. This seems to come through experience and a certain mindset. If we embrace the struggle that we learn.
