Everyone I know has an equal amount of strengths and weaknesses. How you live your life will depend on which you focus. If you focus on your weaknesses it gives them power and they can overwhelm and discourage you. If you focus on your strengths, you can lead a very productive life.
A couple who focuses on each other's strengths has twice as many strengths together. The weaknesses become less important. If they focus on each other's weaknesses they have twice as many weaknesses and it is hard enough to live with our own weaknesses. A couple with twice as many strengths is powerful and can live with confidence and joy.
