You've got to be willing to stay committed to someone over the long run, and sometimes it doesn't work out. But often if you become real honest with yourself and honest with each other, and put aside whatever personal hurt and disappointment you have to really understand yourself and your spouse, it can be the most wonderful experience you've ever had.
Maintain a good balance. A personal life adds dimensions to your professional life and vice versa. It helps nurture creativity through a deeper understanding of yourself.
A talent somewhat above mediocrity, shrewd and not too sensitive, is more likely to rise in the world than genius, which is apt to be perturbable and to wear itself out before fruition.
