''I manage and make sacrifices.
''I was supposed to go to the Smithsonian museum to meet the US president, but I couldn't go because my kid was sick.''
Despite being content with her life, the 37-year-old beauty still wants to ''do better''.

Since beginning her career on 'Mad Men', January thinks she has become a much better person.
