I think Charlie from Perks of Being a Wallflower is a definite INFP. I relate to him a bit too much. Also, Kat from 10 Things I Hate About You. I think Hazel from The Fault in Our Stars is a likely INFP. I would also say that, in real life, Heath Ledger, Kurt Cobain, Gerard Way from My Chemical Romance, and Ed Sheeran are good examples.
