Love deepens towards permanence
This is how we are: we fall in love with each other's strengths, but love deepens towards permanence when we fall in love with each other's weaknesses.
Each person, no matter how old, has an important work to do. This good work not only accomplishes something needed in the world, but completes something in us. The work we do in the world, when it is true vocation, always corresponds in some mysterious way to the work that goes on within us.
