"Dive In" is that moment when you surrender your fears. You shake your head, laughing at how silly and stressed you've been because without warning, the internal storm has ended and you just get it.
Like that moment after a warm rain, the clouds part, the sun shines through the clouds, and life glows again. The path ahead is clear, and all the bullshit falls away.
If you've been waiting for a moment like that – an epiphany that's long over do – maybe turn on "Dive In" and fake it until you make it. First part of getting what you want is believing that you can.
