Are you a younger adult? One thing that may surprise you with a decade or so behind you is how much of the big stuff was only ever a few solid weeks of pushing away.

Building and running a company worth lots of money when we sold it, yes, took 8 years. But getting the company into the right trajectory to do that --- fits and starts, blind alleys aside --- was nothing like that much work.

Some things take "10,000 hours" to get good at, but a lot of really valuable stuff takes more like 100.
