Let's be candid - platitudes are people's way of trying to control their chaos, ignorance, and fear. It's what gets them through the day so they figure the rest of us will benefit from it too.
Point 11 is absolutely right. Everyone should have more fun. This is why I'm fucking off at work right now and posting here.
The shit about the 5 closest people to you puts blame on the reader. It makes you self-analyze under the duress of guilt and shame. It should always be re-written that the five closest people to you can affect your happiness, wellbeing and health so please be kind to yourself and don't let anyone else do anything less. And also sometimes you gotta look at those five people and cut bait for your own life to thrive.
It's all about the delivery whether a statement with the same concept has a supportive overtone or a shaming overtone.
