"Hard times create strong men." You hear this a lot in a generational, society-wide context. But it applies individually as well. Your biggest challenges and setbacks create you. To truly be strong is to struggle and come back better. Strong men aren't born, they're forged.

"Good times create weak men." Your strength will require consistent vigilance. Success is too valuable to be held by idle, clumsy hands. If you rest for too long, your strength will erode. With comfort comes atrophy. With atrophy comes decline. With decline comes hard times.
