What if it were possible to get grit from a pill? People who have taken it and come off of it are saying that they haven't reverted. You get good at what you practice, which is as true for grit as it is of anything else. If some people need assistance in getting that practice, this can probably help them. I've taken ritalin for ADHD for a long time, and if I don't take my treatment, I'm still far more focused and productive than I ever was before treatment, because I developed habits through the medication that stuck. I wouldn't be surprised if something similar were at work here.
