I remember once in Waymouth Street I was approached by a sales guy who asked me a few questions.
What would you like more of?
In the morning how would you like to feel at the end of each day?
What do you want from your personal relationships?
And after I'd answered those questions I got:
"So I will show you a way to get all these, come with me"
And he walked into the building. I think he expected me to follow him.
I think the sales guy was counting on "the IKEA effect".
When you put some energy into an activity, you value the result of that activity more.
If you spend an hour assembling a bookshelf, you'll value it more than one that just turned up.
