A pop culture reference that is relevant is Drew Lynch the comedian on Americans Got Talent. He is doing a great job persevering through his stutter. You can see his videos here: https://m.youtube.com/results?q=drew%20lynch&sm=3 His story is super touching and inspirational. I would suggest watching the AGT segments in order. You can also vote for him tonight I believe (we watch on hulu so not sure the exact dates)
