[1] For two years, he worked as an editor at the publishing company Český spisovatel; after that, he was able to support himself  as a professional author.

Viewegh said that when he thinks about the fact that 90% of people with a ruptured aorta do not survive, he does not worry about criticism, the tabloids, or politics anymore.

[3] His most famous works include Báječná léta pod psa, Výchova dívek v Čechách (Bringing Up Girls in Bohemia, 1994), and Román pro ženy (A Novel for Women, 2001).

[3] Nápady laskavého čtenáře (Thoughts of a Loving Reader, 1993) and Nové nápady laskavého čtenáře (New Thoughts of a Loving Reader, 2000) are both examples of literary parody, in which Viewegh parodies famous Czech and world authors.

Additionally, he has published several autobiographical works, each capturing a small portion of his life in diary format.

The general consensus is that the quality of his writing has also declined; however, some argue that his works are less successful due to poor promotion from his publisher.

[8] Viewegh’s 1992 novel Báječná léta pod psa uses humor to criticize conditions in Czechoslovakia under communism.

Viewegh was unhappy as a writer under communism, but likes the liberties of post-communist Czechoslovakia and the Czech Republic.

[citation needed] In his column for Lidové noviny (Czech newspaper and online news site) published on 1 October 2018, Viewegh criticised Christine Blasey Ford's allegations of sexual assault against Brett Kavanaugh on the grounds that "putting her in an empty room, groping her, covering her mouth while trying to undress her" was an "innocent high-school petting" and that he thanks God that he, as a pubescent, was free to grope his female schoolmates without endangering his future career, without any "North-American cow" complaining about it.

[10] He has been criticised in turn by criminologist Pavel Houdek in a published open letter, that his views are what makes victims of sexual abuse keep it to themselves.
