People essentially only have experience, not age!
Age is just an empty concept of time and has no value. The essential meaning of life is experience, experience, trial and error, which in turn come from cognition, ambition, courage and execution.
Cognition solves the problem of knowing or not knowing;
Ambition solves the problem of wanting or not wanting;
Courage solves the problem of dare or not;
Execution solves the problem of doing or not doing;
And these four are the source and support of each other.
Many times, if you make a breakthrough in one point, you can drive the improvement of the other three aspects, complementing each other
