People never change unless they want to.
As Simon Sinek points it out, the only way to change human behavior is either through manipulation or inspiration.
So if you really want to change someone’s behavior, never set out to do so. The only thing you can do is to inspire them to have a better future, to be a better person, a better spouse,..
And most of us, we are inspired by people who are winning, who are the best. So go be the best in an area. So best that you inspire others to be like you.
