You don’t get something for nothing.
Take this blog. I spend my time writing and promoting posts, sharing thoughts and advice on life as a freelance copywriter. And I don’t get paid for it.
But I still expect a return. It’s nice to see my subscribers list growing. It’s lovely to get some feedback. It’s great that people share my website through social media, and Google (reluctantly) starts caring about what I do.
If I didn’t believe that blogging delivered some kind of return, I wouldn’t do it. I have better uses for my time.
So you get to read the blog for free.
But not for nothing.
And it turns out that giving something away is a particularly potent form of persuasion.
