Funny but I thought the exact opposite. People believe something much more easily when they want it to be true, so the typical sales approach is to tell people what they want to hear. Ridding your life of whatever seems most fun doesn't seem like cheap advice in that regard.
On the other hand, I think you're spot on with creative types too often getting exploited, and the involvement of ego being such a key factor in why/how we hackers get burned out.
