Write the lessons learned. The mesmerizing content is the content shared, whether there is a return or not. You can either buy someone's attention or you can earn it. If you earn it, it's vastly deeper. You put good stuff out to the cosmos; usually, it will return good stuff. The more you share, the more you get.

Sharing what you learn is a source of energy, not hard work you want to avoid.

As an old saying goes, if you want to learn something, you should try teaching it.
