January Jones feels "insecure" as an actress.
The 'Mad Men' star has admitted joining the film and television industry comes with its unpredictability.
She said: "I have yet to feel I can make a living from this. I still feel like they are going to find me out and I won't be able to support my family in five or ten years.
"There is this insecurity, because this is the job where you put yourself out there to be judged, so we kind of ask for that insecurity."
Whilst the 37-year-old actress feels a little open to criticism in her career, she has revealed she is unsure about marriage but would consider it if the right person came along.
She told the May issue of Marie Claire magazine: "I mean, if someone came along and was obsessed with marrying me, I would think about that.
"But growing up, all my family was married and never really got divorced, so marriage was a big deal, it was something you definitely did, so it's not that I'm afraid of it. I just don't need the tax write-off."
