Thank you for these marvelous hacks, a few of these were unformed at the back of my head for a long time now.

I really like the Second Chances mentality, this line especially:

There are those who tell you to live each day as if it might be your last. I prefer to live each day as if I'm doing it over.

seems like a way to visualize/weaponize a consequentialist viewpoint that's also agreeable to your selves under reflection.

The Split Selves especially crystallized some of the "cooperate with alt-time self-versions" mentality I'm trying to stay aware of.

I do have to say "use with caution": Most of these are hard to execute or maintain consistently, and inevitable failures can end in a feeling of contract breach/lower self-trust/"fuck this shit" attitude and so on.

As such it's important to, um, let go of failure? I mean maybe analyze what went wrong, but definitely skip the punishment and just go to "lesson learned, sins forgiven, lets do our best next time!". At least that seems healthier than guilt/duty as motivation.
