I love the quote: “If you want to build a ship, don’t drum up the men to gather wood, divide the work and give orders. Instead, teach them to yearn for the vast and endless sea.” – Antoine de Saint-Exupery. It embodies the crux of human psychology. You can try to force a hand to do what you want but unless you convince the mind the precipitated action will never be sustainable.
Great post, this goes back to showing empathy when you are asking for something (help with a project, buying a product, blowjobs). Put yourself in their shoes and think "what would it take to make me say yes?"
