I really like these choices. Not just because they resonate with me, but because of the way they make choices in advance to conserve finite willpower. Some observations and further habit-hacks:

1. Nothing wrong with a work uniform, good choice. The same idea didn’t hurt Steve Jobs, who wore his personal uniform at all times. And Chris Rock’s Academy Awards joke about the guys all wearing basically the same thing? Yup. Not an accident.
2. I’m coming to believe, per Nir Eyal’s “Hooked” model, that LinkedIn is the only major social network that should be on my phone. This creates an “air gap” between the designed Trigger (“I’m bored/defocused. What’s going on?”) and the intended Action (“Check Twitter!”), interrupting the reflex with no effort or willpower required. Eyal’s framework is really important when thinking of habits and how to create or change them - applies to Trailhead and to personal life: https://www.linkedin.com/pulse/how-manufacture-desire-nir-eyal
3. I hear you re: writing at night. People who don’t need Salesforce access at the same time can borrow Eyal’s model and no-effort interrupter pattern again - put the router on a timer. It goes off at 9:30 pm or whenever, and on at 6:00 am. So all you can do after it goes off is write. If you really need connectivity, you can just go over to the timer and remove it. But you almost never will, and others will get used to the regularity of it. Also good for encouraging time with one’s spouse.
4. The local community angle is something we should all be thinking about. The last few years in Greece comes to mind as an object example for those paying attention.
