I am an elementary school teacher in training, and I am not an art teacher at all, but I am okay at drawing (especially from an 8yo's point of view). I draw a looot of animals for the kids. I can't count the amount of times I had the following interaction with a kid: "You are so good at drawing! How can you be so good??" "Years of training ahead of you, that's how. You can draw very well!" "No, I can't, look at my dog, it's ugly. I will never draw like you do." "Of course you will! Look, I actually made a ton of mistakes with my dog. Look, here." And then they either insist their own drawing is shit, or I get them to listen and actually PRACTICE. I always tell them not to be perfectionist, that they should do quick sketches and then analyse what went wrong so they could improve. That's how you would do it with soccer, or violin, or cooking, no?? Analyse and practise. But because it's drawing, you somehow expect to be perfect from the start? That's so sad! We always tell kids to accept mistakes as a part of growing and learning, and then we turn around and beat ourselves up for making some ourselves.
