Responding to a post requires more time, effort, and appreciation than clapping. The advice is not original to you else I would not agree. Kudos for saying it. And kudos to me for being man enough to give you credit. I assure you that is not necessarily an abundant trait on social media, as such should be appreciated.
The problem I was alluding to is not knowledge of the advice, but in spite of themselves, if people date and pick early in life they just might not in spite of their best intentions know enough to make the most of the advice.
If you think you are on to something, I suggest you come up with a plan for spreading it — blogs, a book whatever.
All the best.
