"Maturity is perseverance-the ability to sweat out a project or a situation, in spite of heavy opposition and discouraging setbacks, and stick with it until it is finished."

Next Quote

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.
