Another way to put the message of that blog: think of it like making minigames for WarioWare. You have to think small and you're free to be silly and experiment. Metaphorically speaking, a minigame is a very nice looking and tasting candy and usually goes better when you eat one, not a dozen.
I think one artistic area that understands this very well is drawing. You don't start by drawing full scenes with lots of different shading and colors. You start with sketches and simple geometric forms. Then, you learn shading, which can turn a triangle into a cone or pyramid. When you get to drawing characters and people, you'll usually spend a good deal of time on eyes alone, then facial expressions, possibly without the whole head.
A good read and the principles hold for a lot of hobbies. Lots of small projects are more fun, more engaging, and better skill-building experiences than learning how to make a masterpiece from the get-go (woodworking example: a perfect cherry chest of drawers with all wood joinery and a french polish finish.)
