The sign of maturity is a state of being as soft as steel, knowing when to hold your head high and knowing when to lower your head. Softness and hardness go hand in hand, and there is a measure of advance and retreat. It is a humble posture.
As the saying goes: "You can get ahead only if you know how to lower your head." Sometimes lowering your head a little is a kind of tolerance, a kind of calmness, a kind of avoidance of competition, and a kind of wisdom for survival. Only with a little chance can you stand out.
