Rule #11: Build assets.
Enter product: The holy grail of digital freedom.
A simplified way to think about what's happening across these tiers:
Service is work without process. (getting specific knowledge)
Productized service is work with process. (stabilizing your time & income)
Product is process without work. (buying back your time)
Think about digital assets like a supercharged version of passive investment vehicles like real estate and dividend-paying stocks.
