My mental model for living well: If I repeated my actions from this week every week for 52 weeks, where would I be in a year? - Dickie Bush

There's no such thing as failure.

You either win or you learn.

Bad copywriting:

• Here's my product
• Here's what it does
• Here's what's so good about it

Good copywriting:

• Here's your problem
• Here's the benefit of solving it
• Here's why what you've tried has failed
• And by the way here's a product that will help you solve it

Twitter is the ultimate idea refinery.

There's no better place to get rapid market validation on an idea you're exploring.

And because of this, you should never invest time writing something long-form that then "flops."

If it does, you didn't validate market demand beforehand.
