Right back atcha, bro; your willful ignorance of the topic or any other solution is, I would say, a focus of your piece.
Done:
[x] Identify a problem ("overpaid millennial techies don't keep track of their spending because they just can't be arsed")
[x] Waste a bunch of time shipping a mobile app six people will ever use
[x] Write self-important, poorly-copyedited Medium post
These are the most visible parts of the design process, but they won't get you success unless you're reeeeeally good in a room with some pretty rich, dumb motherfuckers. (I am made to understand this is getting harder and harder lately.)
Not done:
[ ] Hard stuff?
[ ] Research design process: what else happens??? (<- this sounds hard)
The difficult, meaningful stuff no one really seems to give much of a shit about anymore. Except, of course, the people making good and interesting work that will actually matter a few years from now, and not just destroy a bunch of wealth and effort. But they don't write Medium posts.
Be more like them.
