There are two things, the actual and the ideal.
To be mature is to see the ideal and live with the actual.
To fail is to accept the actual and reject the ideal,
and to accept only that which is ideal,
and refuse the actual is to be immature.
Do not criticize the actual because you have seen the ideal.
Do not reject the ideal because you see the actual.
Maturity is to live with the actual but hold on to the ideal.
