To me, ideas are worth nothing unless executed. They are just a multiplier. Execution is worth millions.

Explanation:
AWFUL IDEA = -1
WEAK IDEA = 1
SO-SO IDEA = 5
GOOD IDEA = 10
GREAT IDEA = 15
BRILLIANT IDEA = 20
NO EXECUTION = $1
WEAK EXECUTION = $1000
SO-SO- EXECUTION = $10,000
GOOD EXECUTION = $100,000
GREAT EXECUTION = $1,000,000
BRILLIANT EXECUTION = $10,000,000

To make a business, you need to multiply the two.
The most brilliant idea, with no execution, is worth $20.
The most brilliant idea takes great execution to be worth $20,000,000.

That’s why I don’t want to hear people’s ideas.
I’m not interested until I see their execution.
