One word is easier to remember in December than a list of resolutions.
Resolutions are a set of tasks. A word is a filter you can apply to a decision in three seconds.
Choose one that would genuinely change your answers: brave, finish, present, less, ask.
Put it somewhere you look daily and use it out loud when you are deciding.
How to actually do it
01 Choose one word, not a phrase.
02 Write it where you will see it every morning.
03 Use it as the tiebreaker on close decisions.
