At Worldcon 76, I was fortunate to be a speaker on a panel addressing imposter syndrome. The panel was excellently moderated and touched on a number of points that people with imposter syndrome can use to move forward. Some of the techniques discussed to help "make it to the end credits" included using writing as a cathartic release, viewing your insecurities as monsters that you can conquer, #buildaladder by adding rungs - no matter how small - to help you climb out of your darkness, learn to say "thank you" and to accept praise, or to reward yourself with something positive, like "cake".
The Mexicanx Initiative was a scholarship fund started by artist John Picacio to bring more Mexicanx representation in science fiction and fantasy to Worldcon 76. The scholarship was awarded to 50 people of Mexican ancestry and, let me tell you, those 50 people made a HUGE impact. The Mexicanx Initiative made Worldcon 76 a powerful experience for me because I got to see myself represented on those panels, in those stories, in the language, the idioms, the anger at the injustices of deportation, criminalization, forced separation and herding of children from their parents, and so much more.
