What should be a priority in one's life: kids or career?
If not continue his career can not go on. Also, to have a career as a successor must be made certain sacrifices (family, friends, lost time, etc.) and some compromises (and sometimes violations of consciousness).
Children are perhaps the most delicate version because attention may decide the child's future parent / s. Being a parent is not easy (sleepless nights, sacrifices, grief, etc.)
Optimal variant Career and children
A career of life: career parent. Perhaps if we see things from this perspective some parents will be happy with a successful career: career parent. And perhaps beyond media promotions, career parent is the most honorable career in the world.
