You don’t have to burn down the old version of you. You can just stop feeding it.

Dramatic change makes a better story and a worse plan. A habit does not need destroying, it needs its supply withdrawn. The old version of you runs on specific inputs: the accounts you follow, the hours you keep, the people who expect that version to turn up. Take away the inputs and it fades without a fight.

Pick the single biggest thing that feeds the version of you that you are done with. Starve that one for two weeks without telling anybody you are doing it. Quiet changes last longer than announcements.
