Developed a healthy but firm relationship with my employer that I shall not be available outside office hours.
Hacked away at slack to permanently disable notifications and never show the blue distraction dot. Developed an expectation among the team about my responsiveness via slack or email.
Unlearned from my previous job: installing any work related software on my phone.
Adopted a financial lifestyle that prevents me from being a wage slave. This is the most important part, I think. It means all of the above can never be eroded because I'm not afraid to quit/be fired. This means I can stand by my philosophy.
