Tavi Gevinson has recently written about her confidence for the first run of the play "This Is Our Youth" in Chicago.

"I would say out loud because that's when things become true that I am awesome and mighty and cannot be made small," Gevinson wrote in the most recent editor's letter for her website for teenage girls Rookie Mag.

Having started as a fashion blogger at the age of 11, Gevinson plays 18-year-old fashion student Jessica Goldman in the revival of "This Is Our Youth" by Kenneth Lonergan, which premiered Off-Broadway at the Intar Theatre in 1996.

While Gevinson appears to be confident with her performance in the play, her role Jessica is a nervous lady trying to please everyone, especially her demanding mother.

"It's like my instinct is just broken," says Jessica who is yearned for by a 19-year-old tall and gangly boy named Warren Straub played by Michael Cera, according to New York Times.

The story of "This Is Our Youth" revolves around Warren who has stolen $15,000 from his abusive father who kicked him out of the house.

With the amount of money he has, Warren planned to entice Jessica into bed in the apartment of his friend Dennis Ziegler played by Kieran Culkin. Dennis, on the other hand, is an abusive drug dealer and a son of a wealthy and famous artist, according to Huffington Post.

Prior to "This Is Our Youth," Gevinson debuted as an actress in the 2008 short film "First Bass."

In 2012, she voiced a character in the animated short film "Cadaver" and starred in Nicole Holofcener's "Enough Said" opposite Catherine Keener, Toni Collette, "Veep" star Julia Louis-Dreyfus and the late "The Sopranos" actor James Gandolfini.

On the other hand, Cera debuted as an actor in an unpaid appearance in a Tim Hortons summer camp commercial while Culkin's first acting role was in the 1990 film "Home Alone," which stars his older brother, Macaulay.
