Los Angeles, May 12 (AZINS) "Mad Men" actress January Jones had to miss her meeting US President Barack Obama because her son was ill.

The 37-year-old, who raises three-year-old Xander alone, says juggling her personal and professional life is a "challenge" and she is ready to make sacrifices when she needs to, reports femalefirst.co.uk.

"It's a challenge but I'm not the only mother dealing with it. I manage and make sacrifices," Britain's OK! Magazine quoted Jones as saying.

"I was supposed to go to the Smithsonian Museum to meet the US President, but I couldn't go because my kid was sick," she added.

Despite being content with her life, Jones 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," she said.
