Watch this because I’m in it
vs.
I’m in it because you’ll enjoy watching it.

Or, I published a book so I need you to read it
vs.
There’s something you need to read, so I wrote about it.

Or I’m fifty and I just made an album because it was time for me to make one.
vs.
These songs won’t let go of me and I want to share them with you because they matter.
