Marketing to everyone means marketing to nobody.

She is equally direct about family and friends being the least likely people to join anything you start, which is the opposite of what most beginners get told.
The law of attraction posts come from experience rather than theory. She noticed that praying about what she did not want kept producing exactly that, started writing goals down instead, and stopped watching the news altogether.
The post on life choices is the gentlest thing here, written about people whose early decisions closed doors that stayed closed, and it refuses to be smug about it.
