"Follow your bliss"

It's advice from an old person, looking backwards at their life, trying to find a pattern after the fact. What you call "bliss" when you're looking at your future is not the same thing as what you label "bliss" looking back at your past.

"Do what you love for a living and you'll never work a day in your life!"

More bad advice. Do what you love for a living, and you'll never completely relax or be able to simply enjoy the things you love anymore.
