Some of my personal finance rules:
1. most all money goes into index funds. virtually 0 stock picking.
2. stick to a monthly budget
3. meet monthly with spouse to review past spending, discuss if we're happy/not about it, any changes we want
4. try to be intentional about stuff i buy. spend on hobbies that i love, buy stuff that lasts, not disposable amazon junk.
5. assume my private company is worth very little or nothing
6. wanted to maxmize time i can spend without income. very conservative. (even though i know i'll keep working). used to have a sheet that counted the months/years.
7. every month, deposit money into index funds.
8. spend little on things that don't bring joy (luxury clothes, owning a home, jewlery, nice hotels) and a lot of stuff that does (weekly cleaner, nice apartment, eBay clothes, services around the house, trainer)
9. tip a lot
10. say no to most all investments
11. remind myself that money's a tool to help get to the end game, not the end game.
12. don't let money be the number 1, 2, 3 reason to do a project.
Not for everyone, but these rules help me sleep like a baby.
