January Jones had to miss meeting President Barack Obama because her son was ill. The 'Mad Men' actress admits juggling her personal and professional life is a "challenge" and she is ready to make sacrifices when she needs to. She said: "It's a challenge but I'm not the only mother dealing with it. "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 star still wants to "do better". "I want to be happy and I want to be a good mum but I'm also a fairly ambitious person. I want to accomplish things in life. I always have this urge to want to do better."
