The hardest thing about getting things done is convincing other people.
Knowhow (intuitive, situated knowledge borne from experience) is extremely rich... but impossible to transmit to others at even a small fraction of fidelity.
If you have to convince many others before you can do anything, you'll do nothing.
It's liberating to be able to take small, experimental actions yourself.
Then, ideas that turned out to work become a no-brainer for others to double-down on once they're shown to be successful.
