I don't want to diminish artistic projects here. Just knowing how to draw or how to code a game or whatever is not enough to actually finish a project. Especially when other people are involved.
This is something people don't appreciate: being an artist means you have to not only do the artsy skill, but also a fair bit of problem solving, logistics, management, and most importantly, leading. This is the actual hard part of doing anything, but it's not something we are taught to value.
