Cringe is just effort that somebody noticed.

What gets labelled cringe is nearly always somebody caring where it can be seen. The only reliable way to avoid it is to do nothing sincerely, which is why the people most afraid of it end up with the smallest lives. Pointing it out is often a way of hiding that you would not dare.

Do the earnest thing this week: the audition, the post, the question in class, the song you actually like. Expect a flicker of embarrassment and let it pass through instead of editing yourself around it. Notice that the people who mock effort are never the ones making anything.
