One does not care to acknowledge one's mistakes of youth.

Mistakes of Youth is a webcomic started in 2006, revolving around the adventures of Rets, a "borderline hikikomori" otaku with a penchant for lolicon, Tina, a yaoi/shotacon fan who is inexplicably Rets' best friend, Brad, the shopclerk who is constantly irritated by Rets, and Rets' Japanese internet friend Go.

The title is a relatively famous line (quoted twice in Otaku no Video) from Char Aznable of Mobile Suit Gundam.

• Ahoge: On Tina. And Rets, on occasion.
• Animesque
• Anime Hair: All of the characters. Most notably Rets.
• Archive Binge: This Troper in particular. I read the entire 140+ series in one night.
  • With less than 200 strips at this point is incredibly easy read all the series in some hours.
• Art Evolution: Very subtle, but the characters have gradually become prettier.
• Art Shift: Usually for comedic effect.
• Big Ol' Eyebrows: Rets.
• Bishie Sparkle: Issue 8
• Blank White Eyes: Used often. Ties with its Animesque.
• Con Recap: Several instances.
• Dull Eyes of Unhappiness
• Fetish: Rets' obsession with Lolicon.
• GIS Syndrome: For anime posters and box/manga covers. Often also for televisions.
• The Rant: Would be better used to explain the above comic's often obscure joke.
• Red Eyes, Take Warning: On Tina. The warning is duly appreciated.
• Slice of Life
• Strip Archive
• Take That: Often implemented. Especially at Hideki Anno's expense.
  • There's also an especially nasty (though very funny) one against Bee Train, which the author seems to dislike for mediocre production values and perceived repetitiveness of theme.
  • There have been numerous ones directed at Gundam00.
• Poster Gallery Bedroom: Rets' room is covered with loli posters from various anime sources.
• Yaoi Fangirl: Tina
• Yandere: Tina
