Wise People Have Rules For Themselves

That's the title of this post https://www.raptitude.com/2017/07/wise-people-have-rules-for-themselves, from David Cain's blog which I highly recommend.
This is my favorite quote of the post:

But setting rules for yourself is completely different. Freedom is the whole point. Who’s more free? The person determined to live on significantly less than their means, no matter what, or the person who shops like a “free spirit?”

Give it a go!
