Apprentice star Karren Brady is renowned as a workaholic -- but even she branded her return to work three days after giving birth as "shameful".
The businesswoman, who rarely even finds time for a holiday, said she thought her career would be in jeopardy otherwise.
But she admits she made a mistake not to spend more time bonding with her daughter Sophia, who is now 14.
Brady (41) said: "It was a mistake and most people would look on it with shock, as they should. When you're young and in a career, you don't think it will last a lifetime.
"You think it will slip through your fingers if you take time out."
The star, who is pictured on the beach in Mauritius, was interviewed by Hello! as she enjoyed only her third holiday in 15 years -- one of which was her honeymoon.
Football executive Brady recently became a member of Alan Sugar's team for BBC1 series The Apprentice.
The West Ham vice-chairman said: "On the rare occasion I did go away, I'd always be working, on my laptop or BlackBerry, and almost never left the room."
Brady, who also has a son Paolo (11) with her husband of 15 years, Burton Albion manager Paul Peschisolido, said she had now begun to enjoy her holiday time with her latest break.
