About a year ago, I caught up with Ali Abdaal, who is a junior doctor in the Cambridge (UK) area who makes youtube videos about tech, productivity and tips for medical students. At that point in time had 200k subscribers on his Youtube channel. Today, he has more than 550k.
This episode contains some golden advice from Ali about how to get started on any project. It's especially useful for those thinking about starting creative, crowd-fronting projects (i.e. youtube channels, blogs, podcasts).
