Billie Piper says striking a balance between work and home life is "unachievable"

Speaking on the Happy Place podcast, she said: "This idea of striking a balance is unachievable. When I am at work all day long that shows in my kids, or in my relationship with my partner ... If I'm not at work, it shows in me. I cry at the end of every day and spend an hour in bed saying, 'I'll be better tomorrow, I swear'. I'm going to read my parenting manual tonight and everything will be better."

Meanwhile, Billie previously revealed she thinks being a parent makes her a "better actor".

She explained: "I would say being a parent makes you a better actor ...

You're exposed to enormous emotions all day long with children and they are an incredible study. Your feelings around them are also really interesting and deeply powerful. Also you have no time. So you do things quickly, effectively, efficiently. Before kids, you would pore over acting roles, spend days thinking how you were going to say a word and what that word meant. I don't personally do that anymore, and I think it's better for it."

And when asked if her ambitions change with age, she added: "Yeah. I would say they're always changing for me, but within the world that I'm working in now I'm quite happy with where I'm at … I’m happy to be able to say it truthfully. I'm able to say that and actually mean it."
