On TikTok, David Milana is known as "the dude that does things on his own". Nights at the AFL, fancy dinner dates, and cinema trips all feature on the 38-year-old Melburnian's social media feed, and in every one of them David is by himself. For more than a year he's been on a mission to overcome his people-pleasing tendencies and his reliance on others for feelings of enjoyment.
