Not just professional athletes and actors thank their mothers for helping them succeed. Women in IT also credit their moms for making them realize they could conquer any career -- even the male-dominated high-tech industry.

"With respect to my career, when I got into computer science there were no women in the program, so she told me to learn to live in a man's world, to always read the headlines -- on the financial pages, sports pages and general news -- and she told me not to get emotional," says Priscilla Milam (above), an IT and service manager for a large gas and power company in Texas. "Still, IT in general is a man's world, and by keeping up with the news and sports, when the pre/post meetings end up in discussions around whether the Astros won or lost or who the Texans drafted, I can participate; and suddenly they see me as part of the group and not an outsider."

According to research released this year by Catalyst, a research firm that advocates breaking barriers for women in technology, the percentage of women holding computing and mathematics occupations has declined since 2000, when women held 30% of these jobs. In 2006, 27% of such positions were occupied by women. The Information Technology Association of America separately reported that "the proportion of women in technology positions in the U.S. has declined from 41% in 1996 to 32% in 2004."

Catalyst says although companies such as HP, IBM, Pitney-Bowes and Texas Instruments work to bring women in-house, many industry watchers struggle to find ways to attract women to high-tech positions.

"Given the increased demand for labor in the technology industry and a nonexistent growth rate in the share of computing jobs held by women, practitioners, journalists and scholars have found themselves asking once again how to entice women into the high-tech industry," a Catalyst report reads.

Milam and other successful women holding high-tech positions say a passion for technology begins early in life and a few encouraging words from their mothers helped them realize they could overcome the challenges inherent in taking on an industry dominated by men. They learned early that just because IT seemed to be a boys' club, it didn't mean that they couldn't make a career in technology accessible for them and future generations of women.
