one of the best teachers I ever had told me the reason kids learn easier than adults is because kids don't worry about messing up the way adults do, so kids learn because they actually spend time familiarizing themself while learning from their mistakes. this helped me learn new skills!
i've struggled with perfectionism my whole life and "I can't do it unless it's good from the start" has kept me from starting SO many projects. It's been a lot easier now that I can go "well literally anything I do will be better than THIS" has really helped my confidence
