Online, you can access over 2,800 TED talks with a grand total of one billion views. But the magic of TED isn’t what takes place on stage for 15 minutes.
No, it’s the little conversations that happen afterwards.
That’s how ideas spread. Not all at once. Drip by drip.
It’s rare for someone to change their mind after one presentation. But if you are lucky, they will go home and read your blog or find a book on the subject.
You get a chance to influence them again.
Change is a matter of frequency and regularity.
