> Obvious miss - "8. Plan a trip – but don't take one" ??
The "but don't take one" part seems unfounded. This is closer to the point:
"One study found that people who just thought about watching their favorite movie actually raised their endorphin levels by 27 percent."
I've found myself feeling good just thinking about something fun or exciting I plan to do. Little things, even just a particularly interesting book I was going to read. Or thinking about parts of a fun side project.

"Don't regret it on your deathbed" - this is a lame feel good idea that directly contradicts most theory.
Live in the moment not (totally) for the future, aka your death bed. You're alive today, live now.
What makes you happy on your death bed doesn't make you happy today.
The point goes on to make a kinda miss. Friends top family for happiness and are more commonly what people have more control over.
