Quotes from the same author

Maturity is the ability to live in peace with that which we cannot change.
 Ann Landers
Maturity is many things. It is the ability to base a judgment on the big picture, the long haul.
 Ann Landers
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.
 Ann Landers
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.
 Ann Landers
Maturity is the ability to make a decision and stand by it. Immature people spend their lives exploring endless possibilities and then doing nothing. Action requires courage. Without courage, little is accomplished.
