As someone who had to deal with a bit of depression in the past I think the article got things backwards. Get motivated first, and as your time becomes limited (instead of just being wasted) discipline and organization naturally follow.
I've found discipline helps most when it's not yet needed. When I have an expanse of time, it's easy to end up being unproductive without discipline. Once I'm working under the pressures of time constraint, discipline is easy because it's necessary and not really an option.
