Simple flow chart showing if you should say yes or no to something using the 80% line.

The 80% Line Test:

In your 20s and 30s, you should probably just say yes to everything. That’s how you figure out what you like and build your career.

But over time, that line should go up.

I call it the 80% line.

If someone hits me up and says, “Hey, want to go for a walk?”

I ask myself: Do I actually want to do that?

If it’s not at least 80%, I say no.

It’s not about thinking you're too good for other people. It’s about being clear on what matters and how limited your time is. I have a kid now. I have family dinners. There’s not a lot of space left.

The more I say no to things below the line, the more I notice something better shows up.
