Maturity is the ability to control anger and settle differences without violence or destruction. The mature person can face unpleasantness, frustration, discomfort and defeat without collapsing or complaining. He/she knows he cannot have everything his/her own way every time. He/she is able to defer to circumstances, to other people-and to time. He/she knows when to compromise and is not too proud to do so.
